The sigma function over a family of cyclic trigonal curves with a singular fiber

Yuri Fedorov, Jiyro Komeda, Shigeki Matsutani +2

In this paper we investigate the behavior of the sigma function over the family of cyclic trigonal curves $X_{s}$ defined by the equation $y^{3} = x (x - s) (x - b_{1}) (x - b_{2})$ in the affine $(…

Jacobi inversion formulae for a curve in Weierstrass normal form

Jiyro Komeda, Shigeki Matsutani

We consider a pointed curve $(X, P)$ which is given by the Weierstrass normal form, $y^{r} + A_{1} (x) y^{r - 1} + A_{2} (x) y^{r - 2} + \dots + A_{r - 1} (x) y + A_{r} (x)$ where $x$ is an aff…
