報告摘要:We propose a new notion of multiplicative connection in the tangent bundle of a Lie groupoid. We identify its infinitesimal analogue and discuss an integration theorem. We also present a bunch of examples. Our results can be easily generalized to multiplicative connections in VB-groupoids. This is the first step towards a theory of linear connections on differentiable stacks (joint work with: F. Pugliese and G. Sparano).
