Abstract: We study the solvability in Sobolev spaces of inverse coefficient problems of finding the solution u(x, t). and the coefficient q(t). in the equation . utt + ϕ(t)uxx + au = f (x, t) + q(t)h(x, t) where ϕ(t). is a nonnegative function. We prove existence and uniqueness theorems for regular solutions, that is, solutions having all the weak derivatives in the sense of Sobolev occurring in the equation. Some possible generalizations of the results are also discussed.
