Factorizations and singular value estimates of operators with Gelfand-Shilov and Pilipović kernels
Yuanyuan Chen, Mikael Signahl, Joachim Toft
We prove that any linear operator with kernel in a Pilipović or Gelfand-Shilov space can be factorized by two operators in the same class. We also give links on numerical approxima…

The Bargmann transform and powers of harmonic oscillator on Gelfand-Shilov subspaces
Carmen Fernandez, Antonio Galbis, Joachim Toft
We consider the counter images $\maclJ (\rr d)$ and $\maclJ _0(\rr d)$ of entire functions with exponential and almost exponential bounds, respectively, under the Bargmann transfor…

Pseudo-differential operators in a Gelfand-Shilov setting
Marco Cappiello, Joachim Toft
We introduce some general classes of pseudodifferential operators with symbols admitting exponential type growth at infinity and we prove mapping properties for these operators on…
