Extending partial edge colorings of cartesian products of graphs
Carl Johan Casselgren, Fikre B. Petros, Samuel A. Fufa
We consider the problem of extending partial edge colorings of cartesian products of graphs. More specifically, we suggest the following Evans-type conjecture: If is a graph wh…

Extending partial edge colorings of iterated cartesian products of cycles and paths
Carl Johan Casselgren, Jonas B. Granholm, Fikre B. Petros
We consider the problem of extending partial edge colorings of iterated cartesian products of even cycles and paths, focusing on the case when the precolored edges satisfy either a…
