Participants are expected to arrive on Sunday, September 18 and to stay until Saturday, September 24. Registration is open until July 31. If you are interested in participating, please contact office@vsmath.at.

Arnaud Chéritat from the Institut de Mathématiques de Toulouse, Mark Peletier from TU Eindhoven, and Karen Vogtmann from the University of Warwick
have already agreed to deliver classes. Please find further details below:

One Dimensional Dynamics
This course will be an introduction to dynamical system through a famous example: iteration of the family of maps $f(x)=a.x.(1-x)$.

Basic notions will be defined, observations made. We will prove some of them and give hints of the method of proof of some others. We will also present open conjectures.

According to the amount of time available, we plan to cover a selection of the following notions:
– local dynamics (analysis)
– kneading invariant (combinatorics and topology)
– entropy
– renormalization

Some Mathematical Aspects of Deep Learning
In these lectures I want to give an introduction to some of the mathematical challenges associated with deep neural networks. This is a beautiful but still badly understood body of methods, tools, and techniques, in which there is much room for mathematics to provide insight.

I will divide the lectures into three parts:
1. Approximation theory for neural networks: Function classes, the universal approximation property, and the role of depth
2. The practice of finding good parameter points: convex and non-convex optimisation, metastability, the role of overparametrization, the role of the size of the noise
3. Wasserstein geometry in deep learning: how the infinite-width makes the landscape simpler, more convex; using log-Sobolev inequalities to study convergence properties of training algorithms.

Moduli Spaces of Graphs and Graph Complexes
Finite graphs describe phenomena in many areas of mathematics and  science. Often specifying some additional structure allows us to make the set of graphs with this structure into a topological space, called a moduli space of graphs. Graph complexes, on the other hand, are algebraic objects (chain complexes) associated to finite graphs with some specified additional structure. Graph complexes  were introduced by Kontsevich in his work on deformation quantization, but have proved to have applications in a wide variety of other areas. These include the study of groups that are important in low-dimensional topology such as automorphism groups of free groups and surface mapping class groups, which act naturally on moduli spaces of graphs. In this course I will describe several flavors of graph complexes and explain how they are related to each other, to various moduli spaces of graphs  and to the relevant groups.
