**Infinite Games**

Prof Imre Leader

Suppose that we are playing a game, but the game might go on forever and so not end. How could we assign a winner or loser in that situation? This sounds like a silly question, but in fact it isn’t, and it leads to some very interesting phenomena.

**Embedding Structures with Distortion**

Dr Andras Zsak

There is a wide variety of structures that are equipped with a distance. A familiar example is three-dimensional Euclidean space: here the distance is the length of the straight line segment joining two points. In this example there is an additional feature: the presence of vector addition and scalar multiplication. There are examples, however, that do not possess such additional features, and it is an important question to determine whether such arbitrary structures can be embedded into ones with a vector structure like Euclidean space. This has consequences for large data, algorithms, compressed sensing, etc., some of which have emerged in unexpected and surprising ways.

**The Prices of Call Options**

Dr Michael Tehranchi

A call option is a basic example of a financial derivative. Black, Scholes and Merton published in 1973 a theory for `rational pricing’ of call options, for which the Nobel Prize was awarded in 1997. This talk will briefly explain this theory, and discuss how the pricing of call options has some interesting mathematical properties – touching on probability, convex analysis and even algebra.

Monday 30 October, Location and Time TBC

**TMS Pub Crawl**

Fancy a bit of relaxation before those Week 5 blues hit? Want to show that maths and the social scene are not separate entities? Come join us on the TMS Michaelmas Pub Crawl. The TMS committee will lead you around a few different pubs, so you can discuss maths, or anything else, in a more social environment.

Monday 6 November, 8:30PM

Dr Jason Miller

Dr Jason Miller is a reader in Statslab, and is also a fellow of Trinity College. His past achievements include being the Poincaré chair at the IHP (Institut Henri Poincaré) in 2015-6. Dr Miller’s main research interest is in probability, in particular stochastic interface models, random walks, mixing times for Markov chains, and interacting particle models.

Monday 13 November, 8:30PM CANCELLED – POSTPONED TO LENT 2018

**The Mathematics of Spin**

Prof Colm-Cille Caulfield

Monday 13 November, 8:00PM

**Film Night – Hidden Figures**

Monday 20 November, 8:30PM

**From Flatland to Our Land: a mathematician’s journey through our changing planet**

Dr Emily Shuckburgh

Mathematics is central to our understanding of the world around us. We live in a vast dynamical system, the many dimensions of which can be interrogated with mathematical tools. In this talk I will consider our changing climate. I will describe the scientific evidence that tells us how and why our climate is changing, and what the future may hold. In this journey I will pause at various waypoints to describe in more detail some of the insight different branches of mathematics are providing. Diverse examples will include applying ideas from dynamical systems research to create novel strategies for measuring the ocean mixing processes that are critical to the flow of heat and carbon through the Earth system, through to employing statistical learning techniques to improve future predictions of Arctic sea ice, currently in perilous decline.

Climate change is one of the greatest challenges facing humanity. Responding to the challenge requires robust scientific evidence to inform policies. Opportunities for mathematicians to contribute to this important issue abound.

**TMS Call My Bluff**

The TMS’s take on the classic BBC quiz show ‘Call my Bluff’ and a fun and relaxed way to end the term; this event involves putting two teams against each other in a game of mathematical lies and deception. For a given mathematical term, one team provides three different ‘definitions’, and the other team must guess which of these is correct.
