Abstract We shall study Markov semigroups generated by foliated diffusions, mainly unequalities relating curvature and dimensions, generalizing results by Ledoux. In the case of Markov semigroup generated by foliated Brownian motion, one expects to get equalities of this kind using foliated Bochner-Weintzenbock identity. We shall consider questions on regularity and ergodicity for harmonic measures as introduced by Lucy Garnett. | |
