Abstract:
We establish the dual notions of scaling and saturation from geometric
control theory in an infinite-dimensional setting. This generalization is
applied to the low-mode control problem in a number of concrete nonlinear
partial differential equations. We also develop applications concerning
associated classes of stochastic partial differential equations (SPDEs). In
particular, we study the support properties of probability laws corresponding
to these SPDEs as well as provide applications concerning the ergodic and
mixing properties of invariant measures for these stochastic systems.
