The Problem of Determining the Coefficient Multiplying a Power-Law Gradient Nonlinearity in a Semilinear Wave Equation
We consider a one-dimensional inverse problem of determining the coefficient multiplying
a power-law gradient nonlinearity in a semilinear wave equation. Theorems on the existence and
uniqueness of the solution of the direct problem and local existence and stability of the solution of
the inverse problem are proved.
