where 0 < | | 1, H(x, y), P (x, y) and Q(x, y) are polynomials in x and y. Let J be a maximal open interval (or a union of several maximal open intervals) on which the level set of the real algebraic curves H(x, y) = h for h ∈ J contains an oval denoted by Γh, that is, Γh = {(x, y) |H(x, y) = h contains an oval, h ∈ J}. The family of ovals Γh for h ∈ J is continuous in h. Such a family is called a period annulus (or a union of several period annuli if J is a union of several maximal open… CONTINUE READING
