    • Sparse initial data identification for parabolic PDE and its finite element approximations 

      Casas E.; Vexler B.; Zuazua E. (Mathematical Control and Related Fields, 2015-12-31)
      We address the problem of inverse source identication for parabolic equations from the optimal control viewpoint employing measures of minimal norm as initial data. We adopt the point of view of approximate controllability ...
    • Spike controls for elliptic and parabolic PDEs 

      Casas E.; Zuazua E. (Systems and Control Letters, 2013-12-31)
      We analyze the use of measures of the minimal norm to control elliptic and parabolic equations. We prove the sparsity of the optimal control. In the parabolic case, we prove that the solution of the optimization problem ...
