Sobolev algebras through heat kernel estimates

Frédéric Bernicot, Thierry Coulhon, Dorothee Frey

On a doubling metric measure space $(M, d, μ)$ endowed with a "carré du champ", let $L$ be the associated Markov generator and $L ˙_{α}^{p} (M, L, μ)$ the correspon…

Riesz transforms through reverse Hölder and Poincaré inequalities

Frédéric Bernicot, Dorothee Frey

We study the boundedness of Riesz transforms in $L^{p}$ for $p > 2$ on a doubling metric measure space endowed with a gradient operator and an injective, $ω$ -accretive operator $L$ sat…
