Title: Smooth Cartan triples

Abstract: Connes’ reconstruction theorem says that you can reconstruct a manifold from a (nice enough) spectral triple. Renault’s theorem says that you can reconstruct a twist over an étale groupoid from a Cartan pair of C*-algebras. In this talk I will discuss how to combine these theorems to recover a Lie twist over an étale Lie groupoid from suitable functional-analytic data. This is joint work with Anna Duwenig.
