Perturbation theory and higher order $S^{p}$ -differentiability of operator functions

Clément Coine

We establish, for $1 < p < \infty$ , higher order $S^{p}$ -differentiability results of the function $φ : t \in R \mapsto f (A + t K) - f (A)$ for selfadjoint operators $A$ …

Schur multipliers on $B (L^{p}, L^{q})$

Clément Coine

Let $(Ω_{1}, F_{1}, μ_{1})$ and $(Ω_{2}, F_{2}, μ_{2})$ be two measure spaces and let $1 \leq p, q \leq + \infty$ . We give a definition of Schur multipliers on $\mathcal{B}(L…
