报告摘要:
Let P be an increasing monotone property. The global strong resilience of G with respect to P is the minimum number r such that by deleting r edges and/or vertices from G one can obtain a graph not having P. 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 talk, we focus on the global strong resilience of G with respect to having a fractional perfect matching, also called FSMP number of G. First we present a sufficient condition, involving the independent number, to determine the FSMP number of (δ−2) -fault Hamiltonian graphs with minimum degree δ≥2, and then we can derive the FSMP number of some networks, which generalize some known results.
