Period matrix of the Jacobian variety of a curve

Click For Summary
SUMMARY

The discussion focuses on computing the period matrix of the Jacobian variety of a smooth algebraic manifold X, specifically in relation to the Kawazumi-Zhang invariant of Riemann surfaces. Key resources mentioned include algorithms on algebraic varieties, particularly the book by Davenport, which discusses the Jacobian and provides an extensive list of references. The paper by Gross, along with its appendix by Rohrlich, is highlighted for its relevance to the computation of abelian integrals. Additionally, Mumford's "Lectures on Theta Functions, Volume II" is recommended for its explicit construction of the Jacobi variety of hyperelliptic curves.

Consider an algebraic variety, X which is a smooth algebraic manifold specified as the zero set of a known polynomial.

I would appreciate resource recommendations preferably or an outline of approaches as to how one can compute the period matrix of X, or more precisely, of the Jacobian variety of the curve.

My motivation is I am studying the Kawazumi-Zhang invariant (related to the Faltings invariant) of Riemann surfaces, which can be expressed as a Fourier series in the period matrix, and thus if I can evaluate the period matrix \Omega of the algebraic manifold, then I can compute its Kawazumi-Zhang invariant, numerically.

Not sure whether it helps, but I've found

which deals with algorithms on algebraic varieties in the sense, that it is less about the mathematics but more about actual algorithms. In the section which is about the Jacobian (p. 106 ff.) Davenport refers to

https://www.amazon.com/dp/1614276129/?tag=pfamazon01-20

However, the latter might be more about boundaries than actual algorithms. A suspicion I have due to the year of its original publication (1959). E.g. the first one proves an upper bound on ##|Jac(C)|_K##. In any case Davenport provides a long list of references, which might be the starting point for further searches.

The question of explicit computation of "abelian integrals", as they are usually called, is one I know little about, but the following paper of Gross may be relevant. It contains an appendix by Rohrlich treating such "computations" in a special case, and also references a paper of Weil on this topic, [W3] in the bibliography of Gross's paper.

Mumford's Lectures on Theta functions, volume II, gives an explicit construction, also following Weil, of the Jacobi variety of a hyperelliptic curve, (the projective closure of the locus) defined by an equation of form Y^2 = f(X), for a polynomial f. Maybe it could be useful.
