Integrals of nonlinear equations of evolution and solitary waves

Integrals of nonlinear equations of evolution and solitary waves ~ In Section 1 we present a general principle for associating nonlinear equations of evolutions with linear operators so that the eigenvalues of the linear operator are integrals of the nonlinear equation. A striking instance of such a procedure is the discovery by Gardner, ... Download Integrals of nonlinear equations of evolution and solitary waves
