Twisted Bredon-Illman Cohomology is a Morita Invariant
Carla Farsi, Laura Scull, Jordan Watts
We show that the twisted Bredon-Illman cohomology defined by Mukherjee-Mukherjee applied to compact Lie group action groupoids is Morita-invariant. This cohomology uses coefficient…

Euler characteristics of linear symplectic quotients and -spaces
Carla Farsi, Hannah Mobley, Christopher Seaton
We give explicit computations of the -Euler characteristic of several families of orbit space definable translation groupoids. These include the translation groupoids associate…
