We study a type of polynomial Li(e)nard system of degree m with polynomial perturbations of degree n.We prove that such systems can have at most n+1-([ n+1/
This talk is concerned with the upper bound of the number of limit cycles in unfolding of codimension 3 planar singularities with nilpotent linear parts,whi
Recurrent dynamics(periodic,almost periodic,almost automorphic,Birkhoff recurrent,Poisson stable motions etc)play important roles in the study of differenti
In this talk we will show the existence of random attractors for a large class of locally monotone stochastic partial differential equations perturbed by ad
In this talk we discuss the mechanical complexity in a periodic-excited horizontal impact pair with dry friction.The impact pair studied models the motions
In this talk,we will review some results on the continuity of entropy,and give some characteristic of entropy of dynamics on the line.The entropy map h is t
