1. Some results about dissipativity of Kolmogorov operators Creator: Da Prato, Giuseppe and Tubaro, Luciano Format: bez média and svazek Type: model:article and TEXT Subject: Kolmogorov equations, invatiant measures, and $m$-dissipativity Language: English Description: Given a Hilbert space $H$ with a Borel probability measure $\nu $, we prove the $m$-dissipativity in $L^1(H, \nu )$ of a Kolmogorov operator $K$ that is a perturbation, not necessarily of gradient type, of an Ornstein-Uhlenbeck operator.
