Weighted Estimates for Operator-Valued Fourier Multipliers

Stephan Fackler, Tuomas P. Hytönen, Nick Lindemulder

We establish Littlewood-Paley decompositions for Muckenhoupt weights in the setting of UMD spaces. As a consequence we obtain two-weight variants of the Mikhlin multiplier theorem…

Off-diagonal sharp two-weight estimates for sparse operators

Stephan Fackler, Tuomas P. Hytönen

For a class of sparse operators including majorants of singular integral, square function, and fractional integral operators in a uniform manner, we prove off-diagonal two-weight e…

A Short Counterexample to the Inverse Generator Problem on non-Hilbertian Reflexive $L^{p}$ -spaces

Stephan Fackler

We show that the bilateral shift group on $L^{p} (R)$ for $p \in (1, \infty) ∖ {2}$ provides a counterexample to the inverse generator problem.
