Taming infinities

**Further information:**Some physical and mathematical theories have the unfortunate feature that if one takes them at face value, many quantities of interest appear to be infinite! Various techniques, usually going under the common name of “renormalisation” have been developed over the years to address this, allowing mathematicians and physicists to tame these infinities. We will tip our toes into some of the mathematical aspects of these techniques and we will see how they have recently been used to make precise analytical statements about the solutions of some equations whose meaning was not even clear until recently.

Renormalisation and the Euler-Maclaurin formula on cones

**Further information:**[based on joint work with Li Guo and Bin Zhang] We apply to the study of exponential sums on lattice points in convex rational polyhedral cones, the generalised algebraic approach of Connes and Kreimer to perturbative quantum field theory. For this purpose we equip the space of cones with a connected coalgebra structure. The algebraic Birkhoff factorisation of Connes and Kreimer adapted and generalised to this context then gives rise to a convolution factorisation of exponential sums on lattice points in cones. We show that this factorisation coincides with the classical Euler-Maclaurin formula generalised to convex rational polyhedral cones by Berline and Vergne by means of an interpolating holomorphic function. We define renormalised conical zeta values at non-positive integers as the Taylor coefficients at zero of the interpolating holomorphic function. When restricted to Chen cones, this yields yet another way to renormalise multiple zeta values at non-positive integers.

The Shape of Data

**Further information:**There has been a great deal of attention paid to 'Big Data' over the last few years. However, often as not, the problem with the analysis of data is not as much the size as the complexity of the data. Even very small data sets can exhibit substantial complexity. There is therefore a need for methods for representing complex data sets, beyond the usual linear or even polynomial models. The mathematical notion of shape, encoded in a metric, provides a very useful way to represent complex data sets. On the other hand, Topology is the mathematical sub discipline which concerns itself with studying shape, in all dimensions. In recent years, methods from topology have been adapted to the study of data sets, i.e. finite metric spaces. In this talk, we will discuss what has been done in this direction and what the future might hold, with numerous examples.
