Groups as automorphisms of dessins d'enfants
Alejandro Cañas, Ruben A. Hidalgo, Francisco Javier Turiel +1
It is known that every finite group can be represented as the full group of automorphisms of a suitable compact dessin d'enfant. In this paper, we give a constructive and easy proo…
Quasi-regular Sasakian and K-contact structures on Smale-Barden manifolds
A. Cañas, V. Muñoz, M. Schütt +1
Smale-Barden manifolds are simply-connected closed 5-manifolds. It is an important and difficult question to decide when a Smale-Barden manifold admits a Sasakian or a K-contact st…
A K-contact simply connected 5-manifold with no semi-regular Sasakian structure
Alejandro Cañas, Vicente Muñoz, Juan Rojo +1
We construct the first example of a 5-dimensional simply connected compact manifold that admits a K-contact structure but does not admit a semi-regular Sasakian structure. For this…
