一个阿贝尔积分根的数目的下界(A lower bound for the number of zeroes about an Abelian integral)
Hopf bifurcation is an important part of bifurcation theory of dynamical systems. Almost all known works are concerned with the bifurcation and number of limit cycles near a nondegenerate focus or center. In this paper, we study a polynomial near-Hamiltonian system , , where H(x, y) = y2/2+ x2k/(2k)...
