Identification for a Nonlinear Periodic Wave Equation

Identification for a Nonlinear Periodic Wave Equation

This work is concerned with an approximation process for the identification of nonlinearities in the nonlinear periodic wave equation. It is based on the least-squares approach and on a splitting method. A numerical algorithm of gradient type and the numerical implementation are given.
