Edge-dominating cycles, k-walks and Hamilton prisms in 2K2-free graphs
We show that an edge-dominating cycle in a 2K22K2-free graph can be found in polynomial time; this implies that every 1k−11k−1-tough 2K22K2-free graph admits a kk-walk, and it can be found in polynomial time. For this class of graphs, this proves a long-standing conjecture due to Jackson and Wormald...
