Abstract

Results have been obtained for certain second order hyperbolic systems with viscous dumping which imply that one can increase 'at will' the margin of stability of arbitrarily finite modes of the damped wave equation (those presumed 'dominant') by means of certain type of the boundary feedback, while the remaining new modes approach asymptotically the original ones from the left of the vertical axis Rez = -k. Numerical testing of the constructive procedure is in the process of being implemented by a Ph.D. student. (Author)
