Characterizing minimally 1-factorable \(r\)-regular bipartite graphs
The author considers the problem of classifying \(r\)-regular bigraphs which are minimally 1-factorable. A graph is called minimally 1-factorable, if it has a 1-factorisation and every 1-factor lies in a unique 1-factorisation. Minimally 1-factorable cubic graphs of girth 4 are classified.
