Erhaltung stetiger Symmetrien bei Gibbsschen Punktprozessen in zwei Dimensionen
Erhaltung stetiger Symmetrien bei Gibbsschen Punktprozessen in zwei Dimensionen
The conservation of continuous symmetries in two-dimensional systems with interaction is a classical subject of statistical mechanics. Here we establish such a result for internal transformations and spatial translations of Gibbsian systems of marked particles with two body-interaction, where the interesting cases of of singular, hard-core and discontinuous interaction are included.

Abstract

The conservation of continuous symmetries in two-dimensional systems with interaction is a classical subject of statistical mechanics. Here we establish such a result for internal transformations and spatial translations of Gibbsian systems of marked particles with two body-interaction, where the interesting cases of of singular, hard-core and discontinuous interaction are included.
