A groupoid approach to pseudodifferential operators

, 2017
The tangent groupoid is a geometric device for glueing a pseudodifferential operator to its principal symbol, via a deformation family. We will discuss a converse to this: briefly, pseudodifferential kernels are precisely those distributions that extend

Coxeter n-cubes and Signed Groupoid-Sets

We investigate mathematical constructions that are related to a class of groupoids called generalized Brink-Howlett groupoids. Generalzied Brink-Howlett groupoids are groupoids that are built from the data of a Coxeter system.

The bicategory of Lie groupoids within diffeological groupoids

Journal of Geometry and Physics
We consider the localisation of the 2-category of diffeological groupoids at weak equivalences from the perspective of anafunctors, and with this language, prove that the localisation of the 2-category of Lie groupoids is an essentially full sub-bicategory of that of diffeological groupoids.

An equivalence relation and groupoid on simplicial morphisms

In this work, we examine the simplicial morphisms homotopies. Firstly, we give the homotopy of free simplicial morphisms and later show that this homotopy relation indicates an equivalence.

Topological rigidity of automorphism systems

Nantong Daxue xuebao. Ziran kexue ban
This paper studies the automorphism actions of countable discrete groups on the étale equivalence relations on compact metric spaces. First, the notion of continuous strong orbit equivalence for automorphism systems is introduced and it is proved that ...
