From this point of view equations for cpL(X) are just relations among the theta functions. For applications for example on moduli problems one would like to have, that the coefficients of these relations are values of certain theta functions determined by L at the point 0 in V. Classically such equations are called theta relations. Examples are, first of all, Riemann's theta relations. These are certain quadratic equations, valid for L = M", with n ^ 4 even and some ample line b ndle M on X. With only a few exceptions, all theta relations can be deduced from the identities of Riemann (see [M 3], p. 211). An obvious exception is the plane cubic equation for an elliptic curve.
