Solution of Mumford's second problem
Abstract
A complete solution of Mumford's second problem about representation of theta derivatives with rational characteristics in terms of theta constants with rational characteristics is found. An explicit formula for computing such an expression for theta derivative with an arbitrary rational characteristic is derived, and illustrated with examples. Expressions for theta derivatives appear to be homogeneous of degree 3 with respect to theta constants.
