About pseudo-Riemannian Lichnerowicz conjecture
Published 3 Nov 2012 in math.DG | (1211.0635v1)
Abstract: We construct the first known examples of compact pseudo-Riemannian manifolds having an essential group of conformal transformations, and which are not conformally flat. Our examples cover all types $(p,q)$, with $2 \leq p \leq q$.
