Haupt showed that a vector with complex entries ( w 1, ⋯, w g, z 1, ⋯, z g) is the period row of some holomorphic differential with respect to a canonical homology basis on some closed Riemann surface of genus g if and only if. (b) no transformation corresponding to a change of canonical basis will bring the ... Webcanonical homology basis was found together with the intersection matrix for that basis, J A. Here we give an algorithm to replace the pair (M A,J A) with the pair (M,J)where M is unique and J is the intersection matrix for a canonical homology basis. (Received February 03, 2007) 1

WebA canonical homology basis of K is a set {A¡,B¡} of cycles that generate H(K) modulo the dividing cycles with A¡ x A¡ = B¡ x B¡ = 0, A¡ x Bj = 8{J. (The symbol x refers to the intersection number. A dividing cycle is a cycle homol- ogous to a cycle lying outside of any finite subcomplex.) Webthe sigma function is defined by specifying a canonical homology basis, it does not depend on the choice of it. For some class of algebraic curves, such as (n,s) curves, the modular invariance is expressed in a more strong form. Namely the Taylor coefficients of the sigma function become polynomials of coefficients of the defining
