Pseudodifferential operators associated with a semigroup of operators

Frederic Bernicot, Dorothee Frey

Related to a semigroup of operators on a metric measure space, we define and study pseudodifferential operators (including the setting of Riemannian manifold, fractals, graphs ...)…

Paraproducts via $H^{\infty}$ -functional calculus

Dorothee Frey

Let $X$ be a space of homogeneous type and let $L$ be a sectorial operator with bounded holomorphic functional calculus on $L^{2} (X)$ . We assume that the semigroup $\{e^{-tL}\}_{t>0}…

A T(1)-Theorem for non-integral operators

Dorothee Frey, Peer Christian Kunstmann

Let $X$ be a space of homogeneous type and let $L$ be a sectorial operator with bounded holomorphic functional calculus on $L^{2} (X)$ . We assume that the semigroup $\{e^{-tL}\}_{t>0}…
