Universal families of rayless graphs
Leandro Fiorini Aurichi, Guilherme Eduardo Pinto
We study the existence and cardinality of universal families for classes of rayless graphs. It is known, by a result of Diestel, Halin, and Vogler, that the class of countable rayl…
On orientations preserving edge-connectivity in infinite graphs
Leandro Aurichi, Paulo Magalhães Júnior, Guilherme Eduardo Pinto
We prove that every 2k-edge-connected graph with countably many edge-ends admits a k-arc-connected orientation, extending the previous result by Assem, Koloschin and Pitz that also…
On cycle covers of infinite bipartite graphs
Leandro Aurichi, Paulo Magalhães Júnior, Lyubomyr Zdomskyy
Given a graph and a subset of vertices of with size at least two, we denote by the set of vertices of that have at least two neighbors in . We say tha…
