Stationary phase with Cauchy singularity. A critical point of signature
Christian Klein, Johannes Sjöstrand, Maher Zerzeri
Asymptotic expressions for an integral appearing in the solution of a d-bar problem are presented. The integral is a solid Cauchy transform of a function with a rapidly oscillating…
Discussing semigroup bounds with resolvent estimates
Bernard Helffer, Johannes Sjöstrand, Joe Viola
The purpose of this paper is to revisit the proof of the Gearhart-Prüss-Huang-Greiner theorem for a semigroup , following the general idea of the proofs that we have seen in…
Characterizing boundedness of metaplectic Toeplitz operators
Lewis Coburn, Michael Hitrik, Johannes Sjoestrand
We study Toeplitz operators on the Bargmann space, with Toeplitz symbols given by exponentials of complex quadratic forms. We show that the boundedness of the corresponding Weyl sy…
