Heat kernel and Green function estimates on affine buildings of type

Jean-Philippe Anker, Bruno Schapira, Bartosz Trojan

We obtain a global estimate of the transition density associated to a nearest neighbor random walk, called here "simple", on affine buildings of type .…

Distributions that are convolvable with generalized Poisson kernel of solvable extensions of homogeneous Lie groups

Ewa Damek, Jacek Dziubanski, Philippe Jaming +1

In this paper, we characterize the class of distributions on an homogeneous Lie group $\fN$ that can be extended via Poisson integration to a solvable one-dimensional extension $\f…

New Proofs of Davies-Simon's Theorems about Ultracontractivity and Logarithmic Sobolev Inequalities related to Nash Type Inequalities

Patrick Maheux

We present new proofs of two theorems of E.B. Davies and B. Simon about ultracontractivity property for of semigroups of operators and logarithmic Sobolev inequalities with paramet…
