calculus for submarkovian semigroups on weighted spaces
Komla Domelevo, Christoph Kriegler, Stefanie Petermichl
Let be a markovian (resp. submarkovian) semigroup on some -finite measure space . We prove that its negative generator has a bounded $H^\infty(Σ_θ)…
Riesz transforms, Hodge-Dirac operators and functional calculus for multipliers I
Cédric Arhancet, Christoph Kriegler
In this work, we solve the problem explicitly stated at the end of a paper of Junge, Mei and Parcet [JEMS2018, Problem C.5] for a large class of groups including all amenable group…
Dimension free bounds for the vector-valued Hardy-Littlewood maximal operator
Luc Deleaval, Christoph Kriegler
In this article, Fefferman-Stein inequalities in withbounds independent of the dimension are proved, for all $1 \textless{} p, q \textless{} + \infty.…
Spectral multipliers for wave operators
Christoph Kriegler
A classical theorem of Mihlin yields Lp estimates for spectral multipliers Lp(R^d) -> Lp(R^d); g -> F^{-1}[f(| |^2) Fg] in terms of L^\infty bounds of the multiplier function f and…
