We describe and analyze a simple SIS model with treatment.In particular,we give a completely qualitative analysis by means of the theory of asymptotically auton
Non-linear numerical method is applied to solve the viscons-elastic-plastic material impact problem.The finite element simulation agrees with the celebrated Eur
In this paper,a nonlinear predator reproduction and prey competition model with diffusion is discussed.Some existence and non-existence results concing non-cons
A proper k-edge coloring of a graph G is called adjacent vertex distinguishing acyclic edge coloring if there is no 2-colored cycle in G and the color set of ed
In this paper,a difference scheme with nonuniform meshes is proposed for the initial-boundary problem of the nonlinear parabolic system.It is proved that the di
