Seminario di Analisi Algebrica e Complessa
Giovedì 7 Gennaio 2016 alle ore 12:30 in Aula 2BC30, Gerd Schmalz (University of New England - Australia) terrà un seminario dal titolo "Chern-Moser theory for para-CR-manifolds and degenerate multi-contact structures".
Para-CR manifolds are contact manifolds with a direct product structure on the contact distribution. This is analogous to CR manifolds, which have a complex structure on the contact distribution. Para-CR manifolds are of interest in Lagrangian geometry. We have constructed a normal form of the defining equation, similar to the Chern-Moser normal form. Surprisingly, the theory becomes much simpler. In particular, the question of embeddability of abstract para-CR manifolds is rather trivial. This is joint work with Alessandro Ottazzi.
