Bibundles and bibundle gerbes

Michael Murray (University of Adelaide)

Tuesday 15th September, 2009 16:00-17:00 Mathematics Building, room 204


Bibundles are principal G bundles with commuting left and right G actions. They are arise naturally when one tries to define a non-abelian generalisation of bundle gerbes. In this talk I will consider their properties and, in particular, their tendency not to exist. If there is time I will talk about the connection with bibundle gerbes or non-abelian bundle gerbes.
