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…
A density counterpart of the Scheepers covering property
Leandro Aurichi, Fortunato Maesano, Lyubomyr Zdomskyy
We introduce a density counterpart of the Scheepers covering property and study its relations to known combinatorial density property. In par…
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…
