Title:
Towards the rare interaction limit of a billiard ball-piston model
Abstract:
A feature of the work of Joska Fritz that has always been very much inspirational for me is to consider problems that have a strong physics motivation, in particular to aim at the derivation of the macroscopic laws of nature from microscopic dynamical principles. Our work in progress -- joint with P. Nandori, D. Szasz and I.P. Toth -- has a long term goal of such a flavour. In my talk I would like to describe the billiard model that we consider, the Markov jump process that arises from it in the limit of rare ball-piston interactions and, if time permits, some of the technical challenges encountered.

Stefano Olla
Title:
Five variations on a Joska theme
Abstract:
Joska has been inspiring my (and others) work on hydrodynamic limits. I will present some recent results strictly related to Joska work, in particular on the hyperbolic scaling.

Szász Domokos
Title:
Excerpts about Jóska from the 70's and 80's
Abstract:
My reminscences will be focused 1. on the one hand around our joint activities founding the Budapest school in mathe-
matical statistical physics and 2. on the other hand around Jóska's breakthrough results, joint with Dobrushin, on the solution of infinite systems of Newton's equations in dimensions one and two.

Tóth Bálint
Title:
Compensated compactness in hydrodynamic limits
Abstract:
I will present a short survey of Jóska's innovative approach to hydrodynamic limit in the Eulerian scaling regime for cases when ordered coupling due to attractiveness is not available.
