This paper concerns limit cycle bifurcations by perturbing a piecewise linear Hamiltonian system. We first obtain all phase portraits of the unperturbed system having at least one family of periodic orbits. By using the first-order Melnikov function

We consider a class of discontinuous Liénard systems and study the number of limit cycles bifurcated from the origin when parameters vary. We establish a method of studying cyclicity of the system at the origin. As an application, we discuss some di

This paper first investigates all possible phase portraits of a class of planar quintic vector field given by x ˙ = ( 1 + 2 b x 2 + 2 d x 4 ) y , y ˙ = − 2 ( 2 a x 2 + b y 2 + 3 c x 4 + 2 d x 2 y 2 ) x , a , b , c , d ∈ R . Then, we study the b
