The last few years have witnessed an impressively high level of advances in the study of the dynamics of mathematical billiards, shedding new light on their profound connections with important problems in geometry, analysis, and mathematical physics. Moreover, billiard-type dynamics is ubiquitous and is significant in the analysis of many physical systems and for real-life applications, for instance in geometric optics.
Some of these questions have recently experienced a renaissance thanks to important breakthroughs that have given a new boost to the research on these topics; it is therefore very timely and even urgent to grasp this moment, in order to capitalize on and further our understanding. The manifold nature of these subjects requires a deep interaction between different – but very much related – research communities. Our program aims to bridge this gap and provide a unique opportunity for this diverse expertise to interact and effectively integrate, a fundamental step in order to tackle several longstanding questions and explore the new interesting directions that are emerging. We plan to organize several activities that should foster this hybridization of knowledge, including introductory courses on selected topics, which could be particularly beneficial for graduate students and early-career researchers, weekly seminars and suitably focused working groups. We also plan to organize an international one-week Workshop: Mathematical billiards: at the crossroads of dynamics, geometry, analysis, and mathematical physics: November 13 – 17, 2023 to present the current state of the research on these topics and the most recent advances.
