Weight Functions in Time-Frequency Analysis
Karlheinz Gröchenig
We discuss the most common types of weight functions in harmonic analysis and how they occur in \tfa . As a general rule, submultiplicative weights characterize algebra properties,…
Quantitative Estimates for the Finite Section Method
Karlheinz Gröchenig, Ziemowit Rzeszotnik, Thomas Strohmer
The finite section method is a classical scheme to approximate the solution of an infinite system of linear equations. We present quantitative estimates for the rate of the converg…
Unimodular Fourier multipliers for modulation spaces
Arpad Benyi, Karlheinz Gröchenig, Kasso Okoudjou +1
We investigate the boundedness of unimodular Fourier multipliers on modulation spaces. Surprisingly, the multipliers with general symbol , where , are bound…
Pseudodifferential Operators on Locally Compact Abelian Groups and Sjoestrand's Symbol Class
Karlheinz Grochenig, Thomas Strohmer
We investigate pseudodifferential operators on arbitrary locally compact abelian groups. As symbol classes for the Kohn-Nirenberg calculus we introduce a version of Sjoestrand's cl…
