| Abstract: | J.R.CANNON and P.DUCHATEAU discussed the inverse problem of the equation utt-uxx=s(u) to determine an unknown source s(u).We used the method of characteristic curves in the bounded domain to get the existence and uniqueness of the solution for the above inverse problem. |

| Keywords: | partial differential equation unknown source inverse problem |
