    • Exact Controllability of the Time Discrete Wave Equation: A Multiplier Approach 

      Zhang X.; Zheng C.; Zuazua E. (Computational Methods in Applied Sciences, 2010-12-31)
      In this paper we summarize our recent results on the exact boundary controllability of a trapezoidal time discrete wave equation in a bounded domain. It is shown that the projection of the solution in an appropriate space ...
