Controllability of linear distributed systems in classes of generalized actions (Q5951337)

The authors give some insight into some problems and methods connected with the controllability of distributed linear systems in classes of concentrated actions. Moreover, they obtain positive results on the final controllability in a finite time for systems described by hyperbolic and pseudohyperbolic equations. The authors also illustrate several statements of problems of controllability for the case of concentrated actions of pseudoparabolic systems. The approach proposed is based on the theory of negative and positive spaces and a priori inequalities with negative norms.
