A matching M of a graph G is a dominating induced matching DIM of G if every edge of G is either in M or adjacent with exactly one edge in M. We prove sharp upper bounds on the number µG of DIMs of a graph G and characterize all extremal graphs. Our results imply that if G is a graph of order n, then µG﾿3n3; µG﾿4n5 provided G is triangle-free; and µG﾿4n-15 provided n﾿9 and G is connected. |
