Abelian Functions for Purely Trigonal Curves of Genus Three
- Mathematics
- 2006
We develop the theory of generalized Weierstrass $\sigma$ and $\wp$ functions defined on a trigonal curve of genus three. The specific example of the `` purely trigonal\rq\rq curve $y^3=x^4+\lambda_3…
Identities for hyperelliptic ℘-functions of genus one, two and three in covariant form
- Mathematics
- 2008
We give a covariant treatment of the quadratic differential identities satisfied by the ℘-functions on the Jacobian of smooth hyperelliptic curves of genus ⩽3.
p-ADIC DIFFERENCE-DIFFERENCE LOTKA-VOLTERRA EQUATION AND ULTRA-DISCRETE LIMIT
- Mathematics
- 1999
We study the difference-difference Lotka-Volterra equations in p-adic number space and its p-adic valuation version. We point out that the structure of the space given by taking the ultra-discrete…
Abelian Functions for Trigonal Curves of Genus Three

We develop the theory of generalized Weierstrass sigma- and \wp-functions defined on a trigonal curve of genus three. In particular we give a list of the associated partial differential equations…
Toda Equations and σ-Functions of Genera One and Two
- Mathematics
- 2003
Abstract We study the Toda equations in the continuous level, discrete level and ultradiscrete level in terms of elliptic and hyperelliptic σ and ψ functions of genera one and two. The ultradiscrete…
Isogenies of certain K3 surfaces of rank 18
- MathematicsResearch in the Mathematical Sciences
- 2021
We construct geometric isogenies between three types of two-parameter families of K3 surfaces of Picard rank 18. One is the family of Kummer surfaces associated with Jacobians of genus-two curves…
Differential equations of genus four hyperelliptic ℘ functions

- 2021
It is shown that some differential equations are satisfied for general genus and the Hirota form is not enough to characterize the integrable differential equations.
Analytical and number-theoretical properties of the two-dimensional sigma function
- Mathematics
- 2020
This survey is devoted to the classical and modern problems related to the entire function ${\sigma({\bf u};\lambda)}$, defined by a family of nonsingular algebraic curves of genus $2$, where ${\bf…
Jacobi Inversion Formulae for a Curve in Weierstrass Normal Form
