Cricket Match

It is a long standing tradition of the TMS and the Adams Society (the mathematical society of St John’s College) to hold an annual cricket match. This year it will be hosted by the TMS on the Old Fields located on Grange Road opposite the Burrell’s Field Porter’s Lodge. The match will start at 10:30 when George Fortune will bowl an apple as the first ball. Food will be provided, so come and cheer us on!

There are still a few spots left on the TMS team. If you are interested in playing, please email Jonathan Zheng at yz460

Double Talk Week!

The Trinity Mathematical Society has a blockbuster week with two talks from both the former Lucasian Professor of Mathematics, Prof. Michael Green, and the current Lucasian Professor of Mathematics, Prof. Mike Cates. (For those of you who haven’t heard of this Professorship, former holders include Isaac Newton, George Stokes, Paul Dirac and Stephen Hawking.) At 8:30PM on Monday 29 February, Prof. Green will be speaking to us at the Winstanley Lecture Theatre, Trinity College. On Tuesday 1 March at 7pm, Prof. Mike Cates will be speaking at MR2, CMS. Refreshments for both talks will be available 15 minutes before the talk.

8:30pm Monday 29 February, Winstanley Lecture Theatre
Speaker: Prof. Michael Green (DAMTP)
Title: The Scope of String Theory

Abstract: This talk will explain why string theory is such a compelling approach to understanding the fundamental particles and the physical forces, even though it is not yet a complete theory and it has yet to make precise experimental predictions. It will give an overview of the theory, illustrating how it describes physics at ultra-short distances in a manner that is radically different from more conventional theories. I will illustrate how the structure of string theory is influencing our understanding of quantum gravity as well as having profound connections with aspects of modern mathematics. The talk will end with an overview of recent ideas, which suggest that the string theory may have applications in areas of physics far removed from the ones it was originally intended for.

7:00pm Tuesday 1 March, MR2 (Wolfson Room), CMS
Speaker: Prof. Mike Cates (DAMTP)
Title: Mathematical Models of Cellular Locomotion
Abstract: Many types of cell in our bodies are not static but actively move around. The effects can be good, such as when immune cells search and destroy invading organisms, or bad, such as when cancer cells spread to distant parts of the body. Many biochemical circuits are implicated in cell movement, but cell fragments with no such circuits also move spontaneously — the cellular equivalent of a headless chicken. This observation suggests the presence of an autonomous “motility engine” whose operation is controlled, but not maintained, by the complex biochemical circuits present in real cells. I shall describe a simplified mathematical model for this engine, using ideas borrowed from the study of liquid crystalline materials, as found in every mobile phone and laptop screen.

Hope to see you all there!

TMS Annual Symposium 2016 – Update

As you might already know, the Annual TMS Symposium will be held in the Winstanley Lecture Theatre, Trinity College on Sunday 21 February. The Symposium will begin at 10:30am and end at 5:30pm so that those attending the dinner will have ample time to get ready. (More details on timing below). We will have a variety of speakers – both fellows and PhD students – across a broad spectrum of mathematical topics.

Fellows: Prof. Malcolm Perry (DAMTP), Dr. Thomas Forster (DPMMS)
PhD Students: Joy Thompson, Patrick Short, Lawrence Barrott

Our key-note speaker will be Professor Miles Reid FRS from the University of Warwick. He will be speaking on the topic of “Finite subgroups of SL(2,CC) and SL(3,CC) and their role in algebraic geometry”. His abstract (which he has kindly written for us in LaTeX) can be found attached.

One of our sponsors, ATASS Sports, has also sent a speaker, Dr. Jonathan Nelson, for the Symposium. Details are below.

Title: Smashing the racket: Detecting match-fixing in tennis via in-play betting irregularities
Abstract: An unfortunate consequence of the recent growth in tennis betting markets has been a heightened incentive for match-fixing – particularly at lower levels of the sport, where earnings are modest, and where the market for one match may dwarf the prize money for an entire tournament. Against this backdrop, an unscrupulous player may be tempted to profit from their position of influence by secretly agreeing to “throw” a particular match, with a complicit third party betting on the result.
This talk summarises the results of a match-fixing study spanning over 5,000 in-play tennis betting markets. After developing a natural point-by-point probabilistic model, featuring novel mechanisms for selecting parameters robustly from the data, we demonstrate that the observed market trajectories correlate extremely closely with this model. We argue that substantial discrepancies represent a “red flag” that something is amiss – either an injury, or something more covert. We also provide visualisations of recent matches where the market evolved pathologically, and assess the evidence that these matches were fixed.

The talks will occur in three blocks (the full schedule and details of each talk will be released very shortly). The order of the talks will roughly alternate between fellows and PhD students.

Block 1: 10:30am – 12:00pm (2 talks)
Lunch
Block 2: 1:00pm – 2:30pm (2 talks)
Break
Block 3: 3:00pm – 5:30pm (3 talks)

There will be drinks and refreshments served in before and after each block. I should note now the Symposium is free for both members and non-members and so please feel welcome to invite people who have not had the chance to visit many Monday talks due to scheduled commitments. I have to say that this year’s symposium looks brilliant and that I will be very tempted to attend all the talks. Moreover, this could be your last chance to see our outgoing TMS President Josh Lam, who will be delighting us with his presence throughout the day and the dinner in the evening. I hope to see you all in droves!MilesReid

Prof. Martin Hyland (DPMMS) – Why Euclid was a genius and (maybe) other stories

Hi all!

The Trinity Mathematical Society is continuing its run of great speakers with Prof. Martin Hyland (DPMMS) coming to talk to us at 8:30PM Monday 8 February in the Winstanley Lecture Theatre, Trinity College. Note that, at the talk, our President Josh Lam will be announcing the time and date the tickets for the TMS Annual DInner will be released. (Last year the tickets were sold out within ten minutes!)

Speaker: Prof. Martin Hyland (DPMMS)
Title: Why Euclid was a genius and (maybe) other stories
Abstract: It is often said that we know very little about Euclid. But we do have (most of) his Elements – perhaps the most widely studied secular book of all time. I claim that it is the expression of a remarkable mathematical personality. There are two distinct proofs of Pythagoras’ Theorem in Euclid’s Elements. I believe that we can reconstruct Euclid’s thinking in giving these two proofs. When we do so, we see what is an unrecognised depth to Euclid: not only was he a remarkable geometer and arithmetician but he also had the instincts of a modern logician.

As always, there will be complimentary port and juice served before the talk at 8:15PM. This talk is for members only, but there will be a chance to sign-up for TMS membership for £2.50. So, come on down to the Winstanley this Monday if you’d like to listen!

Double Talk Week!

The TMS are proud to present two talks in the coming week. In addition to our usual Monday night talk, given by Prof. Ray Goldstein, we will also be having a special event on Tuesday evening, given by Prof. Don Zagier of the Max Planck Institute for Mathematics (MPIM) in Bonn. They both promise to be fantastic events and, if nothing else, you will have the excuse to see TMS’s one and only Joshua Lam as many as two times a week. More details for these two events are as follows: Monday 1st Feb 8.30pm in the Winstanley Lecture Theatre.

Speaker: Prof. Ray Goldstein FRS (Schlumberger Professor of Complex Physical Systems, DAMTP)

Title: Upside down and inside out: the biomechanics of cell sheet folding

Abstract:  Deformations of cell sheets are ubiquitous in early animal development, often arising from a complex and poorly understood interplay of cell shape changes, division, and migration. In this talk I will describe an approach to understanding such problems based on perhaps the simplest example of cell sheet folding: the “inversion” process of the algal genus Volvox, during which spherical embryos literally turn themselves inside out through a process hypothesized to arise from cell shape changes alone.  Through a combination of light sheet microscopy and elasticity theory a quantitative understanding of this process is now emerging.

Tuesday 2nd Feb in MR2, Centre for Mathematical Sciences (time TBC)
Speaker: Prof. Don Zagier (MPIM, Bonn)

Title: Sums of squares and sums of cubes

Abstract to follow, but here is a biography to whet your mathematical appetite:

Prof. Zagier finished high school aged 13 and subsequently studied at MIT for three years, completing his bachelor’s and master’s degrees at the age of 16. He then received his Phd under Friedrich Hirzebruch aged 20 and was named professor when he was 24. He has been a scientific member of the MPIM in Bonn since its founding and has been one of its directors since 1995.

Prof. Zagier’s main area of work is in number theory, but he has also done extensive work in seemingly unrelated areas. In collaboration with Benedict Gross he proved the Gross-Zagier formula which played an instrumental role in the solution of the Class Number Problem. He has also done work relating modular forms to string theory and black holes. Together with his former doctoral student Maxim Kontsevich he introduced the notion of ‘periods’ in a paper which features, among other things, L-functions and motives. He is perhaps best known for his “one-sentence proof of Fermat’s two squares theorem”. He is the winner of both the Cole Prize and the Von Staudt Prize.

TL;DR:
There will be two talks next week, one by Prof. Ray Goldstein and one by Prof. Don Zagier. More details for the Tuesday talk will follow shortly.

Dr. Stergios Antonakoudis, “On Schmidt’s games, badly approximable numbers & winning sets”

Hi all!

The Trinity Mathematical Society is kicking off our extensive 2016 schedule of mathematical events with a talk from Dr. Stergios Antonakoudis (DPMMS) at 8:30PM Monday 25 January in the Winstanley Lecture Theatre, Trinity College. Further details of the event including the title and abstract can be found below.

Speaker: Dr. Stergios Antonakoudis (DPMMS)
Title: On Schmidt’s games, badly approximable numbers & winning sets.
Abstract: Schmidt introduced a simple and powerful way to study certain important sets of real numbers, that although they exhibit remarkable rigidity features, they are ‘too thin’ to be detected using classical methods in analysis. The set of real numbers which badly approximable by rationals is an important example of such a set. In this talk, we will discuss Schmidt’s games, their applications and generalisations in geometry and dynamics.

I should also note that Dr. Antonakoudis has given enterprising members of the audience a warm-up problem to mull over before the talk: Is every real number the difference of two badly approximable numbers? Use the link below to find the definition of that term.

[1]https://en.wikipedia.org/wiki/Diophantine_approximation#Badly_approximable_numbers

As always, there will be complimentary port and juice served before the talk at 8:15PM. This talk is for members only, but there will be a chance to sign-up for TMS membership for £2.50. So, come on down to the Winstanley this Monday if you’d like to explore this burgeoning area of mathematics!
