Fourier multipliers in Banach function spaces with UMD concavifications
Alex Amenta, Emiel Lorist, Mark Veraar
We prove various extensions of the Coifman-Rubio de Francia-Semmes multiplier theorem to operator-valued multipliers on Banach function spaces. Our results involve a new boundednes…
Rescaled extrapolation for vector-valued functions
Alex Amenta, Emiel Lorist, Mark Veraar
We extend Rubio de Francia's extrapolation theorem for functions valued in UMD Banach function spaces, leading to short proofs of some new and known results. In particular we prove…
- off-diagonal estimates for the Ornstein--Uhlenbeck semigroup: some positive and negative results
Alex Amenta, Jonas Teuwen
We investigate - off-diagonal estimates for the Ornstein-Uhlenbeck semigroup . For sufficiently large (quantified in terms of and ) the…
Non-uniformly local tent spaces
Alex Amenta, Mikko Kemppainen
We develop a theory of `non-uniformly local' tent spaces on metric measure spaces. As our main result, we give a remarkably simple proof of the atomic decomposition.
