内容摘要:

Dynamical systems governed by nonlinear hyperbolic like systems are considered. The distinctive features of the dynamics under consideration are :potential supercriticality of the nonlinear forces and lack of dissipativity. This renders standard methods in the theory of attractors for dynamical systems non-applicable. The goal is to provide new tools which will allow to overcome the difficulties. These will be illustrated by examples arising in applications such as : (i) control of noise in an acoustic chamber and (ii) suppression of turbulence/flutter in flow structure interactions.
