Convergence to Equilibrium of Infinite System of Interacting Diffusions
František Žák · arXiv (Cornell University) · 2015
We develop and implement new probabilistic strategy for proving ergodicity results for interacting diffusion processes on unbounded lattice. The concept of the solution used is rather weak as we construct the process as a solution to suitable infnite dimensional martingale problem. However the techniques allow us to consider cases where the generator of the particle is degenerate elliptic operator. As a model example we present operators arising from the Heisenberg group. In the last section we mention some further examples that can be handled using our methods.
