Complementation of the subspace of radial multipliers in the space of Fourier multipliers on
Cédric Arhancet, Christoph Kriegler
In this short note, we prove that the subspace of radial multipliers is contractively complemented in the space of Fourier multipliers on the Bochner space $\mathrm{L}^p(\mathbb{R}…
Hörmander functional calculus on UMD lattice valued spaces under generalised Gaussian estimates
Luc Deleaval, Mikko Kemppainen, Christoph Kriegler
We consider self-adjoint semigroups acting on and satisfying (generalised) Gaussian estimates, where is a metric measure space of homogeneous type of…
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…
