DESCRIPTION:Speakers: Alfonso Garmendia (CRM Barcelona)\n\nHigher Differen
 tial Geometry Seminar\nThis talk\, based on joint work with Francesco Catt
 afi\, presents an extension of the classical correspondence between vector
  bundles and principal bundles to the Lie groupoid setting. To achieve thi
 s\, we introduced the notion of a PB-groupoid with a structural Lie 2-grou
 poid\, establishing a correspondence between VB-groupoids and PB-groupoids
 . This framework enhances our understanding of VB-groupoids\, which play a
  fundamental role in Poisson geometry\, and provides a natural perspective
  on the tangent space of smooth symmetries.\n\nhttps://math-events.uni-bon
