Differentiation of genus 3 hyperelliptic functions

We give an explicit solution to the problem of differentiation of hyperelliptic functions in genus 3 case. It is a genus 3 analogue of the result of Frobenius and Stickelberger (J Reine Angew Math

A PERIODICITY PROBLEM FOR THE KORTEWEG–DE VRIES AND STURM–LIOUVILLE EQUATIONS. THEIR CONNECTION WITH ALGEBRAIC GEOMETRY

1. As was shown in the remarkable communication [4] the Cauchy problem for the Korteweg–de Vries (KdV) equation ut = 6uux−uxxx, familiar in theory of nonlinear waves, is closely linked with a study

Polynomial dynamical systems and the Korteweg—de Vries equation

We explicitly construct polynomial vector fields Lk, k = 0, 1, 2, 3, 4, 6, on the complex linear space C6 with coordinates X = (x2, x3, x4) and Z = (z4, z5, z6). The fields Lk are linearly

w-function of the KDV hierarchy

In the present paper we construct a family of differential commuting multidimensional operators of order 3, which is closely related to the KdV hierarchy. We find a common eigenfunction of this

Solution of the problem of differentiation of Abelian functions over parameters for families of (n, s)-curves

We consider a wide class of models of plane algebraic curves, so-called (n, s)-curves. The case (2, 3) is the classical Weierstrass model of an elliptic curve. On the basis of the theory of

NON-LINEAR EQUATIONS OF KORTEWEG-DE VRIES TYPE, FINITE-ZONE LINEAR OPERATORS, AND ABELIAN VARIETIES

The basic content of this survey is an exposition of a recently developed method of constructing a broad class of periodic and almost-periodic solutions of non-linear equations of mathematical

Integrable polynomial Hamiltonian systems and symmetric powers of plane algebraic curves

This survey is devoted to integrable polynomial Hamiltonian systems associated with symmetric powers of plane algebraic curves. We focus our attention on the relations (discovered by the authors)

Integrals of Nonlinear Equations of Evolution and Solitary Waves

In Section 1 we present a general principle for associating nonlinear equations evolutions with linear operators so that the eigenvalues of the linear operator integrals of the nonlinear equation. A

On Algebraic Expressions of Sigma Functions for (n,s) Curves

An expression of the multivariate sigma function associated with a (n,s)-curve is given in terms of algebraic integrals. As a corollary the first term of the series expansion around the origin of the

A Course of Modern Analysis

The volume now gives a somewhat exhaustive account of the various ramifications of the subject, which are set out in an attractive manner and should become indispensable, not only as a textbook for advanced students, but as a work of reference to those whose aim is to extend the knowledge of analysis.
