Chen/Ruan orbifold cohomology of the Bianchi groups
Résumé
We give formulae for the Chen / Ruan orbifold cohomology for the orbifolds given by a Bianchi group acting on a model for its classifying space for proper actions: complex hyperbolic space. The Bianchi groups are the arithmetic groups PSL_2 over rings of integers in imaginary quadratic number fields.
