In recent years, their connecti ons have been studied with fundamental notions in noncommutative geometry such as groupoids and C*-a lgebras. In particular, the class of quantales cor responding to certain very well behaved groupoids (the etale groupoids) has been identified by means of a non-functorial duality. However, there are v ery interesting examples of groupoids that do not belong to this class. For instance, groupoids that arise from group actions on topological spaces. I n a joint work with Riccardo Re, the non-functoria l duality has been extended to these latter groupo ids as well. In the talk, I will introduce this li ne of research, sketch the main ideas of the duali ty, and discuss some examples. http://www.science .uva.nl/research/math/Calendar/colloq/ X-ALT-DESC;FMTTYPE=text/html:\n
