Finding eigenvalue problems for solving nonlinear evolution equations. (English) Zbl 1079.37509

Prog. Theor. Phys. 54, No. 1, 72-78 (1975).

Summary: The problem of determining what nonlinear evolution equations are exactly solvable by inverse scattering techniques is simplified by considering a linear limit. By linearizing a given eigenvalue problem and the associated time evolution operator, it is possible to determine the class of linearized dispersion relation(s) of the exactly solvable nonlinear evolution equations. Examples are given to illustrate the method.
