Abstract: The forward and inverse problems are investigated for the quasilinear wave equation □u−q(x)u2−K∗u=0 where the kernel K(x,t) is represented in the form K(x,t)=p(x)K0(t) with p(x) being a continuous function. The inverse problem is devoted to the determination of the compact functions q(x) and p(x). Traces of the derivative with respect to x of two solutions to the forward initial–boundary value problem related to two arbitrary boundary data are given for x=0 on the finite segment [0,T] as an additional information for the solution to the inverse problem. The conditions for the unique solvability of the forward problem are found. A local existence and uniqueness theorem is proved for the inverse problem.
