Elliptic Boundary Value Problems and Partial Group Actions
Eske Ewert, Anton Yu. Savin, Elmar Schrohe
We consider a smooth compact manifold with boundary, , embedded in a smooth manifold of the same dimension on which an amenable group acts by isometries. We do not assume $M…
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…
Pseudodifferential operators on filtered manifolds as generalized fixed points
Eske Ewert
On filtered manifolds one can define a different notion of order for the differential operators. In this paper, we use generalized fixed point algebras to construct a pseudodiffere…
Pseudo-differential extension for graded nilpotent Lie groups
Eske Ewert
Classical pseudo-differential operators of order zero on a graded nilpotent Lie group form a -subalgebra of the bounded operators on . We show that its -closur…
Coarse geometry and topological phases
Eske Ellen Ewert, Ralf Meyer
We propose the Roe C*-algebra from coarse geometry as a model for topological phases of disordered materials. We explain the robustness of this C*-algebra and formulate the bulk-ed…
