چکیده
In note' I made use of the idea of the product of two constructs in i. ,obtain certain properties of Abelian integrals attached to algebra.. iieties. The present note uses the same method to, obtain further pi perties of such integrals. §1. 1. Let A, B be two homeomorphic absolute manifolds of n dimensions, and consider the product A X B. On this there is a cycle r of n dimensions, homeomorphic to A or B, corresponding to the transformation between A and B implied by their homeomorphism. If a4 (i = 1, Rp), where Rp is the pth Betti number of A, is a base for the p-cycles of A, and b1 (i = 1..., Rp) is the corresponding base for the p-cycles of B, then as, X b_-p (i =1...,Rp; i = 1, . .., Rr_p; p = 0, . .. r) form a base for the r-cycles of A X B. We therefore have

An extended complete Chebyshev system of 3 Abelian integrals related to a non-algebraic Hamiltonian system
In this paper, we study the Chebyshev property of the 3-dimentional vector space $E =langle I_0, I_1, I_2rangle$, where $I_k(h)=int_{H=h}x^ky,dx$ and $H(x,y)=frac{1}{2}y^2+frac{1}{2}(e^{-2x}+1)-e^{-x}$ is a non-algebraic Hamiltonian function. Our main result asserts that $E$ is an extended complete Chebyshev space for $hin(0,frac{1}{2})$. To this end, we use the criterion and tools developed by...
متن کاملLINEAR ESTIMATE OF THE NUMBER OF ZEROS OF ABELIAN INTEGRALS FOR A KIND OF QUINTIC HAMILTONIANS
We consider the number of zeros of the integral $I(h) = oint_{Gamma_h} omega$ of real polynomial form $omega$ of degree not greater than $n$ over a family of vanishing cycles on curves $Gamma_h:$ $y^2+3x^2-x^6=h$, where the integral is considered as a function of the parameter $h$. We prove that the number of zeros of $I(h)$, for $0 < h < 2$, is bounded above by $2[frac{n-1}{2}]+1$.
متن کاملThe Moduli Space of Real Abelian Varieties with Level Structure
The moduli space of principally polarized abelian varieties with real structure and with level N = 4m structure (with m ≥ 1) is shown to coincide with the set of real points of a quasi-projective algebraic variety defined over Q, and to consist of finitely many copies of the quotient of the space GL(n, R)/O(N) (of positive definite symmetric matrices) by the principal congruence subgroup of lev...

In this article we introduce the mixed Hodge structure of the Brieskorn module of a polynomial f in C, where f satisfies a certain regularity condition at infinity (and hence has isolated singularities). We give an algorithm which produces a basis of a localization of the Brieskorn module which is compatible with its mixed Hodge structure. As an application we show that the notion of a Hodge cy...
