Covering-based numbers related to the LS-category of finite spaces
Manuel Cárdenas, Ramón Flores, Antonio Quintero +1
In this paper, Lusternik-Schinrelmann and geometric category of finite spaces are considered. We define new numerical invariants of these spaces derived from the geometric category…

On manifolds with nonhomogeneous factors
M. Cárdenas, F. F. Lasheras, A. Quintero +1
We present simple examples of finite-dimensional connected homogeneous spaces (they are actually topological manifolds) with nonhomogeneous and nonrigid factors. In particular, we…

Amalgamated products and properly 3-realizable groups
M. Cardenas, F. F. Lasheras, A. Quintero +1
In this paper, we show that the class of all properly 3-realizable groups is closed under amalgamated free products (and HNN-extensions) over finite groups. We recall that is s…
