1 DESCRIPTION OF THE PROBLEM
We consider an infinite-dimensional system described by the wave equation on an n–dimensional domain, with mixed boundary control and mixed boundary observation, which has been analyzed (as an example for a certain class of conservative linear systems) in . A somewhat simpler version of this system has appeared (also as an example) in the paper [11, section 7] and a related system has been discussed in .
