This article introduces the notion of a loose family of Engel structures and shows that two such families are Engel homotopic if and only if they are formally homotopic. This impli…
Fundamental groups of formal Legendrian and horizontal embedding spaces
Eduardo Fernández, Javier Martínez-Aguinaga, Francisco Presas
We compute the fundamental group of each connected component of the space of formal Legendrian embeddings in R3. We use it to show that previous examples in the literature of non t…
Geometric quantization of semitoric systems and almost toric manifolds
Eva Miranda, Francisco Presas, Romero Solha
Kostant gave a model for the real geometric quantization associated to polarizations via the cohomology associated to the sheaf of flat sections of a pre-quantum line bundle. This…
