Abstract: In this talk I will report on a series of papers with Hang Wang the aim of which is to study conformal geometry by using tools from noncommutative geometry, and more especially the twisted spectral triples recently introduced by Connes and Moscovici. The main result I will present is the explicit construction of various conformal invariants as a consequence of an index formula in conformal-diffeomorphism invariant geometry. Incidentally, this provides us with a cyclic cohomology interpretation of previous results of Branson-Orsted.
