Here, a(i), (i = 1, 2, 3, 4) and fk (x), (k = 1, 2, 3, 4) are given constants and functions, respectively. The cases where the roots of the characteristic equation are folded are examined and compact expressions for the solutions are obtained. The obtained solutions allow proving the uniqueness and existence of the solutions of the considered problem.eninfo:eu-repo/semantics/closedAccessD'Alembert type solutionFourth order hyperbolic equationConference Object10.1007/978-3-319-62407-5_542-s2.0-85026773598734Q372610409WOS:000451372400054N/A
