AbstractThe zero divisor of the theta function of a compact Riemann surface X of genus g is the canonical theta divisor of Pic$${^{(g-1)}}$$(g-1) up to translation by the Riemann constant $${\Delta}$$Δ for a base point P of X. The complement of the Weierstrass gaps at the base point P gives a numerical semigroup, called the Weierstrass semigroup. It is classically known that the Riemann constant $${\Delta}$$Δ is a half period, namely an element of $${\frac{1}{2} \Gamma_\tau}$$12Γτ , for the… Expand
