# Orthogonal polynomial duality of boundary driven particle systems and non-equilibrium correlations

@article{Floreani2022OrthogonalPD, title={Orthogonal polynomial duality of boundary driven particle systems and non-equilibrium correlations}, author={Simone Floreani and Frank Redig and F. Sau}, journal={Annales de l'Institut Henri Poincar{\'e}, Probabilit{\'e}s et Statistiques}, year={2022} }

We consider symmetric partial exclusion and inclusion processes in a general graph in contact with reservoirs, where we allow both for edge disorder and well-chosen site disorder. We extend the classical dualities to this context and then we derive new orthogonal polynomial dualities. From the classical dualities, we derive the uniqueness of the non-equilibrium steady state and obtain correlation inequalities. Starting from the orthogonal polynomial dualities, we show universal properties of n…
