Shubin calculi for actions of graded Lie groups
Eske Ewert, Philipp Schmitt
In this article, we develop a calculus of Shubin type pseudodifferential operators on certain non-compact spaces, using a groupoid approach similar to the one of van Erp and Yuncke…

Strict quantization of polynomial Poisson structures
Severin Barmeier, Philipp Schmitt
We show how combinatorial star products can be used to obtain strict deformation quantizations of polynomial Poisson structures on , generalizing known results for con…
