Higher rank homogeneous Clifford structures
Andrei Moroianu, Mihaela Pilca
We give an upper bound for the rank of homogeneous (even) Clifford structures on compact manifolds of non-vanishing Euler characteristic. More precisely, we show that if $r=2^a…
Spacetimes with Singularities
Ovidiu Cristinel Stoica
We report on some advances made in the problem of singularities in general relativity. First is introduced the singular semi-Riemannian geometry for metrics which can change their…
The Cauchy problems for Einstein metrics and parallel spinors
Bernd Ammann, Andrei Moroianu, Sergiu Moroianu
We show that in the analytic category, given a Riemannian metric on a hypersurface and a symmetric tensor on , the metric can be locally extended to a…
Symmetries of F-manifolds with eventual identities and special families of connections
Liana David, Ian A. B. Strachan
We construct a duality for F-manifolds with eventual identities and special families of connections and we describe its interactions with several well-known constructions from the…
