Topological realizations of groups in Alexandroff spaces
P. J. Chocano, M. A. Morón, F. R. Ruiz del Portal
We prove that every group can be realized as the homeomorphism group and as the group of (pointed) homotopy classes of (pointed) self-homotopy equivalences of infinitely many non-h…
Reconstruction of compacta by finite approximations and Inverse Persistence
Diego Mondéjar Ruiz, Manuel A. Morón
The aim of this paper is to show how the homotopy type of compact metric spaces can be reconstructed by the inverse limit of an inverse sequence of finite approximations of the cor…
Self-inverse Sheffer sequences and Riordan involutions
Ana Luzon, Manuel A. Moron
In this short note we focus on self-inverse Sheffer sequences and involutions in the Riordan group. We translate the results of Brown and Kuczma on self-inverse sequences of Sheffe…
Uniformly continuous maps between ends of R-trees
Álvaro Martínez Pérez, M. A. Morón
There is a well-known correspondence between infinite trees and ultrametric spaces which can be interpreted as an equivalence of categories and comes from considering the end space…
