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…

Fractional powers on noncommutative $L_{p}$ for $p < 1$

Eric Ricard

We prove that the homogeneous functional calculus associated to $x \mapsto ∣ x ∣^{θ}$ or $x \mapsto sgn (x) ∣ x ∣^{θ}$ for $0 < θ < 1$ is $θ$ -Hölder on selfadjoint elements of noncommuta…

Convergence and divergence of wavelet series: multifractal aspects

Frédéric Bayart

We study the convergence and divergence of the wavelet expansion of a function in a Sobolev or a Besov space from a multifractal point of view. In particular, we give an upper boun…
