Abstract:

 It is proved that in this paper that the lowest upper bound B(3) of the number of zeros of Abelian integrals
I(h)=∮Гh(α+βx+γx2)ydx
satisfies 4≤B(3)≤6, where Γh is the compact component of
H(x, y) = y2/2 + x3/3 + x4/4 =h
α,β,γ are arbitrary real constants.

Key words: Hamiltoniansystem, Abelianintegrals.
