The perturbation of a class of hyper-elliptic Hamilton system with a double eight figure loop
The authors consider the upper bounds of the number of isolated zeros of abelian integrals associated to a class of hyper-elliptic Hamiltonian systems under perturbations. The unperturbed system has a double eight figure loop. The sharp upper bounds are obtained for ten cases that two of five parameters vanish.
