Abstract
By using the methods of Picard-Fuchs equation and Riccati equation, we study the upper bound of the number of zeros for Abelian integrals in a kind of quadratic reversible centers of genus one under polynomial perturbations of degree n. We obtain that the upper bound is 7[(n−3)/2]+5 when n≥5,8 when n=4,5 when n=3,4 when n=2, and 0 when n=1 or n=0, which linearly depends on n.
