The National Workshop: A Concluding Note

“If I feel unhappy, I do mathematics to become happy.  If I am happy, I do mathematics to keep happy”

Alfred Renyi

Dr. Renyi’s words are certainly words to live by, for the participants at the National Workshop. Guided by the Group Theory Gurus from Chennai, Mumbai and Bengaluru, the crowd of 62 undergrad and postgrad students learned something new every minute, young minds being exposed to the brilliance of modern algebraists over the course of 28 and 29 March 2016.

The introductory lecture was delivered by an Old Stephanian and Oxon, Dr. Geetha Venkataraman. Dr. Venkataraman has always been a friend of the Mathematics Society, and by delivering a riveting lecture entitled “Not the Burnside Lemma”, which talks about the role of symmetry in counting mathematical objects, she gave us a flavour of the lectures to come.

The first day saw an interactive lecture by one of India’s youngest but most mathematically mature researchers, Dr. Amritanshu Prasad, from IMSc Chennai. Dr. Prasad, together with his matchstick model of an octahedron, explained the role of group theory in explaining natural symmetry. Solving problems with the help of students, Dr Prasad’s unique approach was well-received by all, a breath of fresh air in an otherwise drab classroom.

Professor JK Verma, the stalwart from IIT-B, was up next, with his talk on the orthogonal group. Professor Verma ensured that students were well aware of the role of linear algebra in group theory. These lectures again, underpinned the inter-connectivity of topics in mathematics, questioning the way things are taught as if they are discrete blocks. The tutorial sessions saw students and faculty members alike solving problems, thus putting what they had learned down in pen and paper.

Last, but not the least, was Professor B Sury, from ISI Bangalore, and a lecture on group theory and its applications to reducibility of integer polynomials over different rings. Professor Sury too delved into linear algebra, and asked students to solve problems on the board, again ensuring that the lecture wasn’t one-sided, and breaking the confidence barrier.

We, at the Mathsoc, are proud to have pulled this Workshop off without a hitch. A shout-out to all our volunteers, who like the folks at IndiGo, ensured that everything was, “on-time”.

A special thank you to Ms Jaspreet Kaur, our staff advisor and Workshop Convener. Ma’am, this Workshop was your brainchild, and wouldn’t have happened without your leadership and persistence in getting the job done.

We’ll sign off now, and hope to pull off a similar feat in the coming academic year.

National Workshop on Group Theory

   The Mathematics Society is devoted to pursuing activities aimed at fostering interest in and creative expression of mathematical ideas, both in college and outside it. We believe that mathematics education is limitless, and should therefore extend beyond the classroom.
   In light of this, we are pleased to present the National Workshop on Group Theory and Its Applications. 
The Workshop would see an audience from all over the country, comprising of undergraduates and postgraduates. It is an event that will be held on a grand scale, over a period of two days: 28-29 March, 2016. This workshop will seek to bring together four researchers from across India with diverse interests that fit into the broad framework of group theory to conduct sessions for the participating students. The classes will be aimed at undergraduate and post graduate students, and will be devoted to some of the motivating ideas and key examples in the area.
 The main aim of this workshop is to systematically expose various areas of Group Theory and their applications to the students . The selected participants will have common research interest but with diversified backgrounds and knowledge, thereby bringing in a wider range of expertise. Our speakers are:
1. Dr. JK Verma (IIT Bombay)
2. Dr. Amritanshu Prasad (IMSc., Chennai)
3. Prof. B Sury (ISI, Bengaluru)
4. Prof. Geetha Venkataraman (Ambedkar University Delhi)
 The prime objective of the workshop is to introduce the basic concepts of the group theory and explore the importance, difficulties and challenges of this innovative research field. Attached is the Schedule for the Workshop, as well as the abstracts for the talks.

“A Mathemusician’s Journey” – A Talk by Dr. Sudeshna Basu

Math and music are usually organized into two separate categories, without obvious overlap. It tends to be that people are good at math and science or art and music, as if the two elements could not be placed together logically. In actuality, math and music are indeed related and we commonly use numbers and math to describe and teach music.


The Mathematics Society of St. Stephen’s College wrapped up its string of events for the present academic session with a talk by Dr. Sudeshna Basu named “A Mathemusician’s Journey”.

Mathemusicians journey


Dr. Sudeshna Basu grew up in Kolkata, India. She started her early musical training under the tutelage of famous Hindustani classical vocalist Smt. Meera Bandyopadhyay of Patiala gharana. After a rigorous training in classical music Dr. Basu started taking Rabindrasangeet lessons under the maestro Sri Ashoketaru Bandyopadhyay.Recently, she started taking lessons on Dhurpad from the famous Gundecha Brothers. She obtained her Ph. D from Indian Statistical Institute, Kolkata. She then went to United States to pursue her academic goals. After teaching at universities in the US, she quit her full time job to dedicate herself whole heartedly to music. She now divides her time between mathematics and music.


Her talk mainly focused on the sub-conscious usage of mathematics in Indian Classical music. Without the boundaries of rhythmic structure – a fundamental equal and regular arrangement of pulse repetition, accent, phrase and duration – music would not be possible.


She illustrated the above with the example of a tihai, which is a rhythmic variation that marks the end of a melody or rhythmic composition, creating a transition to another section of the music. The basic internal format of the tihai is 3 equal repetitions of a rhythmic pattern), interspersed with 2 (usually) equal rests.

For example,

If the phrase is 16 beats long,
like in the rhythmic cycle called Teental,
the outline of a Anagat Tihai might look like 4 2 4 2 4.

Here, each “4” represents a rhythmic pattern that is 4 beats long,
and each “2” represents a rest that is 2 beats long.
(4+2+4+2+4 = 6+6+4 = 12+4 = 16).The start of the next phrase fall exactly on the downbeat.

The mathematician/musician spoke about the influence of music in the lives of various mathematicians in the past including that of Albert Einstein.

He once said that had he not been a scientist, he would have been a musician. “Life without playing music is inconceivable for me,” he declared. “I live my daydreams in music. I see my life in terms of music…I get most joy in life out of music.”


Being a mathematician as well as a musician both Tagore and Einstein had great influence on her. Dr. Basu ended the talk with a slideshow of photographs from her visit to Einstein’s home in Princeton, Mercer County, New Jersey, United States, which included those of Rabindra Nath Tagore’s visit to Einstein’s home in 1930.


To sum it up, the talk was a great experience for math and music enthusiasts.

Dr. Sudeshna Basu’s credit lies in how she juxtaposes her life of a Mathematics teacher at a university in the US and her passion for singing Tagore songs.

As an important part of Integration’15, Pictionary was conducted by The Mathematics Society on 24th February, 2015.

The event which had two rounds ; the preliminary round, and the final round was participated by around 34 teams coming from various colleges across Delhi.
In the first round, one team member chose 5 shapes and directed his teammate to draw the figure, which the latter had to guess. In the second round, one of the team members (randomly chosen using chits) was blindfolded and the figure given to them was to be guessed within a minute. The event was received very well by the audience. People who participated were puzzled whereas the other participants (viewers) were wondering whether the participating team could guess the obvious figure.

DSC_0084 Although, it seemed very easy, but the task given was quite a challenge for one’s communicating skills.

At the end, Edgar (3rd Maths) and Sohan (2nd Maths) from St. Stephen’s college emerged victorious while two IITians from delhi ,Ishank and Shekhar were runners up.

All in all, Pictionary 2015 was handled very effectively and was the most enjoyed event of Integration’15.

Guesstimate 2015 was organised at the Mathematics Society’s annual fest Integration 2015. Guesstimate is a mass appealing event which is a bit different from the traditional guesstimating case studies that are found commonly. Our Guesstimates are more so to do with Mathematics involving your skills to actually use Math and Estimation skills.


The event had a Preliminary Round where all the Teams which participated were given a small sheet to calculate 8 Guesstimations of various types. These were only a small clue of what was to follow for the final rounds and the participants were judged on their proximity to the actual answers.


6 Teams qualified for the finals and the finals had the following 4 rounds:

  1. Mathematical Estimation: Mostly simple Math Questions where calculating the exact value is really not an option.

Eg. 44777883*334456666

  1. Real World Round: You are given a clue and you have to extend and use that information to calculate the actual answer.

Eg. If No. Of restaurants in X is 56, how many restaurants are there in Y.( Given that Y is twice as big as X and is more food crazy)

  1. Fictionate: Your common estimation skills and ability to think of the dimensions of real world objects would help you.

Eg. How many 2 Rupee coins in height would be needed to equal the Great Wall of China

  1. Audio/Visual Round: Based on the clips/sounds given Participants were asked to estimate various facts.

Eg. Participants were shown a clip and asked how many words were spoken in the full video.(Lengths were given)

The event was enjoyable and the weird questions made sure the participants enjoyed the event.

Treasure Hunt


Treasure hunt is the flagship event organised by the mathematics society, St Stephen’s college , under its annual fest Integration. The event attracted maximum participation from colleges across the city.The Mathematics society treasure hunt is known for its clever and fun clues .This is the event where the analytic skills of a person help him to make better judgments,. Treasure hunt was not purely based on mathematical reasoning but on general logic, making it open for everyone to participate. The event saw enthusiastic teams, filled with zest to find each and every clue.


Busy bees could be spotted solving the clues, while some could be spotted chasing each other to reach it to the first place. The clues were strategically placed with the exploration of the college in mind. This allowed the participants to go to the ends of the college.


The event started with the registrations on the 24th February 2015 at 1:45 pm in the SCR lawns. It lasted for more than an hour, and the team with the correct solutions to the clues, who reached first, was declared as the winner. There was a lot of hustle and bustle, with teams trying to outwit each other .the fun element added the cherry on the cake , making the event a success.The participants learned many new things by the end of the treasure hunt.

Mathopolis -The Mathematics Quiz

Mathopolis , the quizzing event at Integration 2015, was held on Monday, 23 February, which was the first day of the Mathematics Society’s annual fest. The quiz featured many teams of two members each, and was evenly contested from the start. The questions revolved around mathematics and its applications, and were as diverse as the field of mathematics itself. From the father of group theory, Niels Henrik Abel, to questions about the null hypothesis in applied statistics, to the “two policemen and a drunk” theorem, the quiz had it all.The quiz was made in a way that included pop culture references and incorporated mathematics and other fields like art and music. The Quiz was seen as a way to spread the beauty of mathematics. Mathematics is always seen as a dry subject so the quiz was a way of popularizing mathematics in India.

The winners were Shannon Sequeira and Abraham Jose, both students of St. Stephen’s College, and the runners-up were Rahul Mehra of St. Stephen’s and Sameer Thomas of Hindu College.

Arithmancy is one of the major events of “Integration”: The Annual Fest of The Mathematics Society. Arithmancy is a maths based event where the participants need to solve math questions to clear the rounds along with the spices of playing stone-paper-scissor-lizard, bidding and the board game. Arithmancy 2015 started off with participation of 25 teams of 2 members each.


The first round was a combination of three sub-rounds. The first sub-round was a very straight forward one where each team had to solve 20 mathematical questions within the given time limit. Use of phone or calculators was not allowed. The second sub-round was cryptography, where the teams had to decode a one liner text. A hint was given in form of a mathematical question, solving which they got a number and using it they had to decode the message. The third sub-round was speed calculations. In the first five questions numbers were being flashed one after other and the teams had to keep on adding them. In the next five questions numbers were displayed along with operators forming an equation. The teams had to solve these equations from left to right without applying BODMAS. After the first round top six teams proceeded to the next round.


The  next round comprised of lot of luck because it involved bidding. One of the team member was supposed to bid and the other team member was to play stone-paper-scissor-lizard against another team. If they win the double of their bided amount is added to their account and if they lose only the bided amount is subtracted. This round ended up with four teams qualifying for the next.

The board game was an inspiration from the snake and ladder one, except the dislocation of ladders and no snakes and dice, In each turn teams had to solve a question correctly to move forward on the board. And if the question is incorrect they move backwards. But the teams had the freedom to choose the level of the question i.e easy, medium and hard. Easy, medium and hard questions corresponded to one, two and three steps respectively. When a team reached ladder they were bound to solve a hard question in order to use it. In case they solve it incorrectly they could not use the ladder.


After all the solving, biding and decoding Arithmancy got over with the winners being Bhavya Madan and Aparna Mishra, Overall it was a  maths based event which had twists and amendments to make it more fun.
