Limit cycles appearing from perturbations of cubic piecewise smooth center with double invariant real straight lines
Jihua Yang, Liqin Zhao
This paper investigates the exact number of limit cycles given by the averaging theory of first order for the piecewise smooth integrable non-Hamiltonian system \begin{eqnarray*} (…

On the number of limit cycles for generic Lotka-Volterra system and Bogdanov-Takens system under perturbations of piecewise smooth polynomials
Shiyou Sui, Jihua Yang, Liqin Zhao
In this paper, we consider the bifurcation of limit cycles for generic L-V system () and B-T system ($\dot{x}=y,~\dot{y}=-…
