We discuss time quasi-periodic solutions to nonlinear Schroedinger (NLS) and nonlinear wave equations (NLW) on the torus in arbitrary dimensions. The latter is hyperbolic and uses additionally, a Diophantine property of algebraic numbers.
Ergodic Theory & Statistical Mechanics
This weekly seminar welcomes many visiting speakers and also provides a forum for results by Princeton/IAS faculty and graduate students. While most talks focus on one of the two namesake topics, there tends to be overlap with other fields. Most recently, talks have included material on celestial mechanics, number theory, probability theory, the Schrodinger equation, spectral theory and Teichmueller theory.
