Complementation of the subspace of radial multipliers in the space of Fourier multipliers on $R^{n}$

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 $L^{p}$ spaces under generalised Gaussian estimates

Luc Deleaval, Mikko Kemppainen, Christoph Kriegler

We consider self-adjoint semigroups $T_{t} = exp (- t A)$ acting on $L^{2} (Ω)$ and satisfying (generalised) Gaussian estimates, where $Ω$ is a metric measure space of homogeneous type of…
