A bicategorical interpretation for relative Cuntz--Pimsner algebras
arXiv:1708.03471 · doi:10.7146/math.scand.a-112630
Abstract
We interpret the construction of relative Cuntz-Pimsner algebras of correspondences in terms of the correspondence bicategory, as a reflector into a certain sub-bicategory. This generalises a previous characterisation of absolute Cuntz-Pimsner algebras of proper correspondences as colimits in the correspondence bicategory.
