报告摘要
A graph G is matching covered if each edge of G is contained in a perfect matching of G. An edge e of a matching covered graph G is removable if G−e is also matching covered. A removable edge e of G is b-invariant if the number of bricks of G−e equals that of G. This report presents several results concerning removable edges and b-invariant edges.
