Maximal Hörmander Functional Calculus on Lp Spaces and UMD Lattices

Luc Deleaval, Christoph Kriegler

Let $A$ be a generator of an analytic semigroup having a H{ö}rmander functional calculus on $X = L^{p} (Ω, Y)$ , where $Y$ is a UMD lattice. Using methods from Banach space geometry in…

$H^{\infty}$ calculus for submarkovian semigroups on weighted $L^{2}$ spaces

Komla Domelevo, Christoph Kriegler, Stefanie Petermichl

Let $(T_{t})_{t \geq 0}$ be a markovian (resp. submarkovian) semigroup on some $σ$ -finite measure space $(Ω, μ)$ . We prove that its negative generator $A$ has a bounded $H^\infty(Σ_θ)…
