We study the problems of identification for the damped sine-Gordon equations with constant parameters. That is, we establish the existence and necessary conditions for the optimal constant parameters based on the fundamental optimal control theory and the transposition method studied in Lions and Magenes [5].
Keywords: sine-Gordon equation, identification problem, optimal parameter, transposition method
