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.
