报告题目：On even cycle decomposable 4-regular line graphs

摘   要：A graph is even cycle decomposable if its edges can be partitioned into cycles of even length. A graph G is strongly even cycle decomposable if every subdivision of G with an even number of edges is even cycle decomposable. Markström conjectured that for any 2-connected cubic graph G, its line graph L(G) is even cycle decomposable. Máčajová and Mazák further asked whether L(G) is strongly even cycle decomposable. In this talk, we will report some recent progress on Markström's conjecture as well as Máčajová and Mazák's question.
