End-faithful spanning trees of countable graphs with prescribed sets of rays
We prove that a countable connected graph has an end-faithful spanning tree that contains a prescribed set of rays whenever this set is countable, and we show that this solution is, in a certain sense, the best possible. This improves a result of Hahn and Širáň Theorem 1.

Equivalences between isomorphism classes on infinite graphs
The paper studies some equivalence relations between isomorphism classes of countable graphs which correspond in a certain sense to various distances between isomorphism classes of finite graphs.

Frutex y caminos nodales.
Dado un grafo G = (X,E) con un solo vértice insaturado p, se estudia el problema de encontrar, para todo x ∈ X, un camino M-alternado par que una x con p. Se halla un algoritmo, y se plantea su aplicación cara a dar una variante del Algoritmo de Edmonds en la que no haya que contraer los pseudovértices.
