Quadratic perturbations of a class of quadratic
reversible systems with one center
Abstract: This paper is concerned with the bifurcation of limit cycles from a class of one-parameter family of quadratic reversible system under quadratic perturbations. The exact upper bound of the number of limit cycles is given.
Keywords: quadratic perturbations,
quadratic reversible system, limit cycle, Abelian integral.
