A Nash-Moser Approach to KAM Theory,s us to construct a set of symplectic coordinates in a neighborhood of the torus in which the Hamiltonian is in a generalized KAM normal form with angle-dependent coefficients. Based on this observation we develop an approach to KAM theory via a Nash-Moser implicit function iterative theorem. The ke

On the Spectral and Orbital Stability of Spatially Periodic Stationary Solutions of Generalized Kor cases for which the skew-symmetric operator . is singular. We assume that . restricted to the orthogonal complement of its kernel has a bounded inverse. With this assumption and some further genericity conditions we (a) derive an unstable eigenvalue count for the appropriate linearized operator, an

Partial Differential Equations with Random Noise in Inflationary Cosmology,rrent paradigm for describing the very early universe, where one is often interested only in the time-dependence of a subsystem. In inflationary cosmology it is assumed that a slowly rolling scalar field leads to an exponential increase in the size of space. At the end of this phase, the scalar fiel
