,Sur Un Probleme D’Elie Cartan, has shown that conversely, the only non-integrable, totally géodésie distributions of hyperplanes in projective space are of this type. The note gives a new proof of Cartan’s result, based on the notion of totally géodesic quasi-connection.Blood-Clot 发表于 2025-3-29 10:01:19
