N ov 1 99 3 Continuous vacua in bilinear soliton equations
We discuss the freedom in the background field (vacuum) on top of which the solitons are built. If the Hirota bilinear form of a soliton equation is given by A(D x)G·F = 0, B(D x)(F ·F − G·G) = 0 where both A and B are even polynomials in their variables, then there can be a continuum of vacua, parametrized by a vacuum angle φ. The ramifications of this freedom on the construction of one-and tw...
متن کاملHirota’s bilinear method and soliton solutions
In this lecture we will first discuss integrability in general, its meaning and significance, and then make some general observations about solitons. We will then introduce Hirota’s bilinear method, which is particularly useful in constructing multisoliton solutions for integrable nonlinear evolution equations. 1 Why is integrability important? In very general terms integrability means regulari...
متن کاملMulti-component generalizations of four integrable differential-difference equations: soliton solutions and bilinear Bäcklund transformations
Bilinear approach is applied to derive integrable multi-component generalizations of the socalled 1+1 dimensional special Toda lattice, the Volterra lattice, a simple differential-difference equation found by Adler, Moser, Weiss, Veselov and Shabat and another integrable lattice reduced from the discrete BKP equation. Their soliton solutions expressed by pfaffians and the corresponding bilinear...
متن کاملBilinear Stochastic Elliptic Equations
We study stochastic elliptic PDEs driven by multiplicative Gaussian white noise. Even the simplest equations driven by this noise often do not have a square-integrable solution and must be solved in special weighted spaces. We demonstrate that the Cameron-Martin version of the Wiener chaos decomposition is an e ective tool to study such equations and present the corresponding solvability results.
متن کاملGeneralized Bilinear Differential Equations
We introduce a kind of bilinear differential equations by generalizing Hirota bilinear operators, and explore when the linear superposition principle can apply to the resulting generalized bilinear differential equations. Together with an algorithm using weights, two examples of generalized bilinear differential equations are computed to shed light on the presented general scheme for constructi...
