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
For analytic differential systems(x)= Ax+f(x)in Fn with F = R or C,we first study the varieties of their partial integrability in a neighborhood of the orig
In this talk,we will introduce a Li′enard System with a symmetric nonlinear center,and discuss the limit cycles from the symmetric nonlinear center under s
Stationary patterns of a two-cell coupled isothermal chemical system with arbitrary powers of autocatalysis are considered.Firstly,we obtain the stability o
