Glowinski, R.; He, J. W.; Lions, J. L. On the controllability of wave models with variable coefficients: a numerical investigation. (English) Zbl 1125.35309 Comput. Appl. Math. 21, No. 1, 191-225 (2002). Summary: This paper is devoted to investigate, computationally, the controllability of wave models with variable coefficient, including some non-controllability situations erising when the coefficients depend on the space variable.
