D. Orlovsky, S. Piskarev, R. Spigler. On approximation of inverse problems for abstract hyperbolic equations // Taiwanese Journal of Mathematics. 2010. Vol. 14, N 3B. 1145-1167.
This paper is devoted to the numerical analysis of inverse problems for abstract hyperbolic differential equations. The presentation exploits general approximation scheme and is based on $C_0$-cosine and $C_0$-semigroup theory within a functional analysis approach. We consider both discretizations as well as in space and time. The discretization in time is considered under the Krein-Fattorini conditions.
