Operator-valued Fourier multipliers of bounded s-variation
Chenxi Deng, Emiel Lorist, Mark Veraar
In this paper, we establish an operator-valued Fourier multiplier theorem in weighted Lebesgue spaces, Besov and Triebel--Lizorkin spaces, assuming the multiplier has …

Improved polynomial decay for unbounded semigroups
Chenxi Deng, Jan Rozendaal, Mark Veraar
We obtain polynomial decay rates for -semigroups, assuming that the resolvent grows polynomially at infinity in the complex right half-plane. Our results do not require the…
