Zappa-Sz\'ep product groupoids and C*-blends [PDF]

open access: yes, 2016
We study the external and internal Zappa-Sz\'ep product of topological groupoids. We show that under natural continuity assumptions the Zappa-Sz\'ep product groupoid is \'etale if and only if the individual groupoids are \'etale.

Cohomology and Decomposition of Tensor Product Representations of SL(2,R) [PDF]

open access: yes, 2002
We analyze the decomposition of tensor products between infinite dimensional (unitary) and finite-dimensional (non-unitary) representations of SL(2,R). Using classical results on indefinite inner product spaces, we derive explicit decomposition formulae,
