Giving an additional condition, a time-dependent coefficient multiplying nonlinear term is determined, and existence and uniqueness theorem for small times is proved. The finite difference method is proposed for solving the inverse problem.eninfo:eu-repo/semantics/closedAccessexistence and uniquenessfinite difference methodFourier methodinverse coefficient problemnonlinear hyperbolic equationExistence and uniqueness of an inverse problem for nonlinear Klein-Gordon equationArticle10.1002/mma.5609421037393753WOS:000470931800018Q2Q1
