DESCRIPTION:Quantales are very simple ordered alge
 bras which can be thought of as pointfree noncommu
 tative topologies. 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
