Infinite dimensional systems of particles with interactions given by Dunkl operators

Abstract: Firstly we consider a finite dimensional Markov semigroup generated by Dunkl laplacian with drift terms. Using gradient bounds we show that for small coefficients this semigroup has an invariant measure. We then extend this analysis to an infinite dimensional semigroup on $(\mathbb{R}^N)^{\mathbb{Z}^d}$ which we construct using gradient bounds, and finally we study the existence of invariant measures and ergodicity properties.
