报告摘要: In this talk, we present some recent results and methods for bifurcations and dynamics of limit cycles in planar Lienard differential systems with Z2-symmetry, including existence, uniqueness, exact number, stability and hyperbolicity of limit cycles. Moreover, using these results for the limit cycles together with other qualitative method and techniques, we can obtain the exact number of limit cycles and further obtain the global dynamics and bifurcations in some polynomial and oscillator Lienard systems.
