Recovering a time- and space-dependent kernel in a hyperbolic integro-differential equation from a restricted Dirichlet-to-Neumann Operator. <i>Electronic Journal of Differential Equations, 2004</i>(67), pp. 1-16.1072-6691https://hdl.handle.net/10877/13420We prove that a space- and time-dependent kernel occurring in a hyperbolic integro-differential equation in three space dimensions can be uniquely reconstructed from the restriction of the Dirichlet-to-Neumann operator of the equation into a set of Dirichlet data of the form of products of a fixed time-dependent coefficient times arbitrary space-dependent functions.Text16 pages1 file (.pdf)enAttribution 4.0 InternationalInverse problemDirichlet-to-Neumann operatorHyperbolic equationsViscoelasticityRecovering a time- and space-dependent kernel in a hyperbolic integro-differential equation from a restricted Dirichlet-to-Neumann OperatorArticle
