In this talk,we are concerned with a singularly perturbed higher-order KdV equation which is considered as a paradigm in nonlinear science and has many appl
In this talk we introduce persistent center problem of planar differential systems,and give answers for some systems and its relation between complex system
In this talk,we will give an analytical proof about the existence of Bogdanov-Takens bifurcation of codimension 3 in a predator-prey model with constant-yie
We shall recall briefly how can be the local phase portraits of the equilibrium points of an analytic differential system in the plane,and we shall put our
In this talk,we shall report some aspects of nonlocal dispersal systems.First,we will present some relations between local(random)and nonlocal dispersal pro
