In this seminar I will introduce transfer operators associated to piecewise monotone interval transformationsand and show that, for a large…

Coherent Sheaves, Quivers and Affine-Yangian Representations – Miroslav Rapcak (CERN)
According to the famous result of Schiffmann and Vasserot, the cohomology of the ADHM moduli space carries the structure of an affine-Yangian module. For the purpose of our talk, it is useful to view this moduli space from a three-dimensional…
Infinity-categories and infinity-operads – Francesca Pratali (Université Sorbonne Paris Nord)
An operad is a structure that consists of abstract operations, each one having a fixed finite number of inputs and one output, as well as maps defining composition laws. A coloured operad is an operad where input elements and the output are allowed…
Stated skein algebras – Francesco Costantino (Université de Toulouse)
In this talk I will recall the notion of skein algebra and skein module of surfaces and of three manifolds…
Dynamics of piecewise affine contractions – José Pedro Romana Gaivão (ISEG, University of Lisbon)
The attractor of any piecewise affine contraction is either a finite set or a Cantor set. It is known that the former case occurs generically, both in metric and topological sense. In this talk we present recent results regarding the Hausdorff…
Hilbert-Kunz density function and its applications to some Hilbert-Kunz multiplicity conjectures – Vijaylaxmi Trivedi (Tata Institute of Fundamental Research, India)
In this talk we introduce a compactly supported and real valued continuous function called Hilbert-Kunz (HK) density function. We briefly describe its properties and its applications to study characteristic p-invariants like HK multiplicity and F…
On finite presentation for the tame fundamental group – Vasudevan Srinivas (Tata Institute of Fundamental Research, India)
This is a report on joint work with H. Esnault and M. Schusterman.Recall that the étale fundamental group of a variety over an algebraically closed field of characteristic 0 is known to be a finitely presented profinite group; this is proved by…

A “matching strategy” for optimal control problems with PDEs as constraints – Santolo Leveque (Scuola Normale Superiore, Pisa)
Saddle-point systems arise quite often in many areas of scientific computing. For instance, this type of system can be found in computational fluid dynamics, constrained optimization, finance, image reconstruction, and many more scientific…
