The sigma function for trigonal cyclic curves

Jiryo Komeda, Shigeki Matsutani, Emma Previato

A recent generalization of the "Kleinian sigma function" involves the choice of a point of a Riemann surface , namely a "pointed curve" . This paper concludes our ex…

The Weierstrass semigroups on double covers of genus two curves

Takeshi Harui, Jiryo Komeda, Akira Ohbuchi

We show that three numerical semigroups <5,6,7,8>, <3,7,8 > and <3,5> are of double covering type, i.e., the Weierstrass semigroups of ramification points on double covers of curve…

Weierstrass semigroups on double covers of genus four curve

S. J. Kim, J. Komeda

Let C be a complete non-singular irreducible curve of genus 4 over an algebraically closed field of characteristic 0. We determine all possible Weierstrass semigroups of ramificati…

Sigma functions for a space curve of type (3, 4, 5)

Shigeki Matsutani, Jiryo Komeda

In this article, a generalized Kleinian sigma function for an affine (3,4,5) space curve of genus 2 was constructed as the simplest example of the sigma function for an affine spac…
