$H^{\infty}$ 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)…

Failure of the matrix weighted bilinear Carleson embedding theorem

Komla Domelevo, Stefanie Petermichl, Kristina Ana Škreb

We prove failure of the natural formulation of a matrix weighted bilinear Carleson embedding theorem, featuring a matrix valued Carleson sequence as well as products of norms for t…
