By means of the existence and uniqueness of semi-global C^1 solution to the mixed initial-boundary value problem with general nonlinear boundary conditions for
Two new hereditary classes of P5-free graphs where the stability number can be found in polynomial time are proposed. They generalize several known results.
By using the continuation theorem of coincidence theory,the existence of a positive periodic solution for a two-patches competition system with diffusion and ti
A labeled graph is an ordered pair (G,L) consisting of a graph G and its labeling L:V(G)→{1,2,...,n},where n=|V(G)|.An increasing nonconsecutive path in a labe
