Abstract

The paper deals with the {\it infinitesimal Hilbert 16th problem}: to find an upper estimate of the number of zeros of an Abelian integral regarded as a function of a parameter. In more details, consider a real polynomial H H of degree n+1 n+1 in the plane, and a continuous family of ovals γt\gamma_t (compact components of level curves H=t H = t) of this polynomial. Consider a polynomial 1-form ω\omega with coefficients of degree at most n.n. Let I(t) = \int_{\gamma_t} \omega. \label{I} The problem is to give an upper estimate of the number of zeros of this integral. We solve a {\it restricted version} of this problem. Namely, the form ω \omega is {\it arbitrary,}, and the polynomial H H, though having an arbitrary degree, is not too close to the hypersurface of degenerate (non ultra-Morse) polynomials. We hope that the solution of the restricted version of the problem is a step to the solution of the complete (nonrestricted) version.
