A weak type $(p, a)$ criterion for operators, and applications

Bernhard H. Haak, El-Maati Ouhabaz

Let $(X, d, μ)$ be a space of homogeneous type and $Ω$ an open subset of $X$ . Given a bounded operator $T : L^{p} (Ω) \to L^{q} (Ω)$ for some $1 \leq p \leq q < \infty$ , we give a criterion…

Maximal regularity for non-autonomous evolution equations

Bernhard Hermann Haak, E. -M. Ouhabaz

We consider the maximal regularity problem for non-autonomous evolution equations of the form $u (t) + A (t) u (t) = f (t)$ with initial data $u (0) = u_0$ . Each operator $A (t)$ is as…

Exact observability, square functions and spectral theory

Bernhard Hermann Haak, El-Maati Ouhabaz

In the first part of this article we introduce the notion of a backward-forward conditioning (BFC) system that generalises the notion of zero-class admissibiliy introduced in [Xu,L…
