Kalmenov (Institute of Math., Almaty, Kazakhstanz) Durvudkhan Suragan (Institute of Math., Almaty, Kazakhstanz) Abstract: In this work we consider an initial-boundary value problem for the one-dimensional wave equation. We prove the uniqueness of the solution and show that the solution coincides with the wave potential. Submitted January 9, 2014. Published February 19, 2014. Math Subject Classifications: 35M10.
