Weighted Modulation Spaces and Pseudo-Differential Operators
Responsible organisation
2003 (English)Report (Other academic)Alternative title
Viktade Modulationsrum och Pseudodifferentialoperatorer (Swedish)
Abstract [en]

The most usual weighted modulation spaces is considered. It is proved that a lot of such spaces can be obtained in a canonical way from the corresponding standard modulation spaces. The results are used to get inclusions between certain modulation spaces and Besov spaces, and for proving continuity properties in pseudo-differential calculus.

Abstract [sv]

I uppsatsen analyseras viktade modulationsrum. Det visas bl a att många av dessa, däribland de viktigaste, kan erhållas på ett naturligt sätt från standardmodulationsrummen. Dessa egenskaper gör att många problem kan omformuleras så att enbart standardmodulationsrum förekommer. I uppsatsen demonstreras detta på inbäddningsrelationer mellan modulationsrum och Sobolevrum/Besovrum, samt nya kontinuitetsresultat inom pseudodifferentialkalkylen och teorin för Toeplitz operatorer. En del uppmärksamhet riktas även till den tvistade faltningsalgebran, som har nära relationer med Weylkalkylen inom teorin för pseudodifferentialoperatorer. Nyckelord: Modulationsrum, pseudodifferentialoperatorer, Toeplitzoperatorer, inbäddningar, faltningar, spåroperatorer
