L. Jodar et P. Almenar, UNIQUENESS OF SOLUTION FOR MIXED PROBLEMS RELATED TO THE GENERALIZED WAVE-EQUATION, Computers & mathematics with applications, 33(4), 1997, pp. 49-51
In this note, the uniqueness of solution for mixed problems recently s
tudied in [1] is proved. This fact guarantees that the numerical solut
ions constructed in [1] converge to the unique solution of the problem
