Nicaise, Serge Boundary exact controllability of interface problems with singularities. I: Addition of the coefficients of singularities. (English) Zbl 0858.93012 SIAM J. Control Optimization 34, No. 5, 1512-1532 (1996). Author’s abstract: We prove the exact controllability by boundary action of hyperbolic interface problems with singularities. The idea is to replace the classical space of controls with the space of their regular parts, which is augmented with the coefficients of singularities. This leads to a classical boundary control but with an internal control, which is a distribution with a support equal to the singular vertices.
