Introduction

The School on Interactions between Dynamical Systems and Partial Differential Equations (JISD) is an international summer school that has taken place at the School of Mathematics and Statistics of the Universitat Politècnica de Catalunya (UPC) since 2002. The last four editions have been held at the Centre de Recerca Matemàtica (CRM).

The JISD is an annual meeting between experts and young researchers in Dynamical Systems and Partial Differential Equations (PDEs). It is designed to encourage and enhance the exchange of knowledge and methods, with the goal of advancing the study of cutting-edge problems in the aforesaid fields of mathematics and with the aim of fostering interaction among the participants. The symposium is aimed at local researchers, as well as scientists from the rest of Spain and foreign countries. It is organized into four advanced courses of about 7 hours and complemented by a poster session by young researchers. Throughout the latest editions, the attendance numbers have ranged between 60 and 100 participants, mostly internationals.

A primary objective of the JISD is to attract talented young researchers who can present a poster to put them in a condition to benefit from exposure to world-leading experts and help them establish working relationships that could prove critical for their short and long-term success. An especially strong effort has been devoted in past years to encourage the participation of undergraduates, PhDs and postdocs from developing countries and, more generally, young researchers who may encounter difficulties in accessing adequate financial support.

lecturers

Marie-Claude Arnaud: Conformal Dynamics

Université Paris Cité

Abstract: Beyond Hamiltonian and symplectic Dynamics, the conformal dynamics study dynamics that multiply a local symplectic form by a factor that is different from 1. This includes for example Hamiltonian systems with friction term. Even if some tools coming from conservative and symplectic dynamics can be used in this setting, some dissipative phenomena appear in is this setting, as attractors. In this course, we will study the conformal dynamics of both classical symplectic manifolds and their extensions, the locally symplectic manifolds. In particular, in the symplectic setting, we introduce and study the natural generalization of Birkhoff attractor in higher dimension. In the locally symplectic setting, we will explain which relation exists between recurrence properties, shape of the orbits and exponential rate of the linearized dynamics (as Lyapunov exponents).

Giovanni Catino: Stable Minimal Hypersurfaces

Politecnico di Milano

Abstract: I will present an overview on the classification problem for stable minimal hypersurfaces in the Euclidean space, starting from the seminal work of Schoen-Simon-Yau in the 70’s to the recent advancements obtained by O. Chodosh and C. Li and by myself in collaboration with P. Mastrolia and A. Roncoroni.

Xavier Ros-Oton: Integro-Differential Elliptic Equations

ICREA – Universitat de Barcelona – Centre de Recerca Matemàtica

Abstract: The aim of this course is to provide an introduction to the regularity theory for integrodifferential elliptic equations. Such a class of equations often arises in Analysis, Probability theory, Mathematical Physics, and in several contexts in applied sciences, and this area of research has attracted great interest in the PDE community in the last 15 years, especially since the first works of Caffarelli and Silvestre on the topic. We will start with the basic theory for linear equations, to then give an overview and prove some results for nonlinear equations, and finally discuss some open problems in this context.

Dmitry Turaev: Wildness and Richness of Chaos

Imperial College London

Abstract: We show how various global and local bifurcations lead to chaos of ultimate richness: one determines, by a simple computation, the effective dimension D of the bifurcational problem (an a priori bound on the number of zero Lyapunov exponents) and then shows that all dynamics possible for all systems in the D-dimensional space can emerge at this bifurcation. The techniques can be applied for constructing deep learning algorithms.
