Bochner-Riesz means on the Heisenberg group
Detlef Müller, Lars Niedorf, Andreas Seeger +1
We prove new boundedness results for Bochner-Riesz means associated with the spectral decomposition of the sub-Laplacian on the Heisenberg group . Our results ho…

-estimates for FIO-cone multipliers
Stefan Buschenhenke, Spyridon Dendrinos, Isroil A. Ikromov +1
The classical cone multipliers are Fourier multiplier operators which localize to narrow -neighborhoods of the truncated light cone in frequency space. By composing such convo…

Bounds on pseudodifferential operators and Fourier restriction for Schatten classes
Detlef Müller
As main result, we show that a pseudodifferential operator in the Weyl calculus, whose symbol has compact Fourier support, lies in the Schatten class if and only if…
