Canonical homology basis
Webcanonical homology basis on S (which has genus 2g - 1 by the Riemann-Hurwitz relation) obtained as follows: 81 is the (unique) lift of twice 61; -1 is either the lift of yi (the two lifts are homologous); vi, 5i+gi are the two lifts of 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

Webto a set of one-cycle representatives of a canonical homology basis as a set of retrosections. Then all possible Riemann matrices for a given surface S, indeed for all surfaces conformally equivalent to S, are obtained by all possible changes in a given set of retrosections for S. Webical homology basis A 1;:::;A g;B 1;:::;B g. Canonical means that the intersection numbers of the paths are A iA j= B iB j= 0; A iB j= i;j= B iA j: (If two oriented paths cross with …
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.)
WebJul 2, 2024 · $\begingroup$ "Canonical" means "not depending on auxiliary choices", thus the map which assigns to a $1$-cycle $\gamma$ (not a line, what is a line on the torus?) … WebA generating set which generates a canonical representative for each element in the homology classes of is subsequently computed. Finally, this generating set is used to compute the desired set of paths. These steps are described in turn in the following subsections. Figure 2.
WebNote that a canonical divisor on X is just the intersection of X with a curve of degree d−3. For quartics this means the intersec-tion of X with a line, giving the canonical embedding. Where do the g 1-forms come from? Theorem. If X is a compact Riemann surface of genus g, then dimΩ(X) = g. Idea of the proof.
