WebHere one constructs a canonical homology basis for a hyperelliptic curve that shows that its periods must satisfy certain constraints and deﬁnes an open set in the Siegel upper half space that cannot contain any period matrices of hyperelliptic curves. 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 duration for long tours in army
