Dear all, This is to announce the availability of a preprint "Connections and path connections in groupoids". Abstract: We describe two gauge theoretic notions of connection in a (differentiable) groupoid. The two notions are related via the notion of holonomy. Holonomy formation (integration) is shown to be inverse of a certain differentiation process. The method is that of Synthetic Differential Geometry, notably in the form of "First Neighbourhood of the Diagonal". The preprint can be dowlnoaded from http://www.imf.au.dk/publs?id=619 or from my home page http://home.imf.au.dk/kock/ Yours Anders
