Determining a nonlinear hyperbolic system with unknown sources and nonlinearity
Determining a nonlinear hyperbolic system with unknown sources and nonlinearity
Abstract This paper is devoted to some inverse boundary problems associated with a timeādependent semilinear hyperbolic equation, where both nonlinearity and sources (including initial displacement and initial velocity) are unknown. It is shown in several generic scenarios that one can uniquely determine the nonlinearity and/or the sources by using passive ā¦
