Summary
Let W(z) be an n x n matrix polynomial with rational coefficients. Denote C the spectral curve $\det \left( w\cdot{\bf 1}-W(z)\right) =0$. Under some natural assumptions about the structure of W(z) we prove that certain combinations of logarithmic derivatives of the Riemann theta-function of C of an arbitrary order starting from the third one all take rational values at the point of the Jacobi variety J(C) specified by the line bundle of eigenvectors of W(z).
