Orbifold Euler characteristics of non-orbifold groupoids
Carla Farsi, Christopher Seaton
For a finitely presented discrete group , we introduce two generalizations of the orbifold Euler characteristic and -orbifold Euler characteristic to a class of proper topolo…

Classifying spaces and Bredon (co)homology for transitive groupoids
Carla Farsi, Laura Scull, Jordan Watts
We define the orbit category for transitive topological groupoids and their equivariant CW-complexes. By using these constructions we define equivariant Bredon homology and cohomol…

Functional equations for orbifold wreath products
Carla Farsi, Christopher Seaton
We present generating functions for extensions of multiplicative invariants of wreath symmetric products of orbifolds presented as the quotient by the locally free action of a comp…
