Fernández Fuertes, Eduardo ; Martínez-Aguinaga, Javier ; Presas, Francisco | Mathematical Sciences Publishers (MSP) | 2020We 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 nontrivial loops of Legendrian embeddings are already nontrivial at th[...]texto impreso
We show the existence of elements of infinite order in some homotopy groups of the contactomorphism group of overtwisted spheres. It follows in particular that the contactomorphism group of some high dimensional overtwisted spheres is not homoto[...]
