Spectral Invariance of Quasi-Banach Algebras for Matrices and Pseudodifferential Operators
Karlheinz Gröchenig, Christine Pfeuffer, Joachim Toft
In the paper we extend the spectral invariance of pseudodifferential operators acting on (non-weighted) classical modulation spaces to allow the Lebesgue exponents to be smaller th…
Pseudo-differentialoperators on Orlicz modulation spaces
Joachim Toft, Rüya Üster
We deduce continuity properties for pseudo-differential operators with symbols in quasi-Banach Orlicz modulation spaces when rely on other quasi-Banach Orlicz modulation spaces. In…
Fourier characterizations of Pilipovic spaces
Joachim Toft, Anupam Gumber
Let be a function or distribution on $\rr d$. We show that belongs to a certain Pilipovi{ć} space, if and only if and suitable partial fractional Fourier transforms of…
An excursion to multiplications and convolutions on modulation spaces
Nenad Teofanov, Joachim Toft
We give a self-contained introduction to (quasi-)Banach modulation spaces of ultradistributions, and review results on boundedness for multiplications and convolutions for elements…
