This paper investigates the global strong resilience of having a fractional perfect matching, as well as the FSMP number and properties of fault Hamiltonian graphs.
The global strong resilience of G with respect to having a fractional perfect matching, also called FSMP number of G, is the minimum number of edges (or resp., edges and/or vertices) whose deletion results in a graph that has no fractional perfect matchings. A graph G is said to be f-fault Hamiltonian if there exists a Hamiltonian cycle in G - F for any set F of edges and/or vertices with |F | <= f. In this paper, we first give a sufficient condition, involving the independent number, to determine the FSMP number of (delta - 2)-fault Hamiltonian graphs with minimum degree delta >= 2 , and then we can derive the FSMP number of some networks, which generalize some known results.
