Title：

Internal waves and circle homeomorphisms

Abstract:

Internal waves are gravity waves that propagate within density-stratified fluids and play a fundamental role in geophysical and astrophysical fluid dynamics. The spectral and evolution theories of internal waves are related to circle homeomorphisms, sometimes referred to as "chess billiards". In this talk, I will introduce recent developments in mathematical theory of two-dimensional internal waves in domains with boundaries, highlighting the “classical-quantum correspondence” between dynamics of internal waves and circle homeomorphisms.

AbstractThe creation and manipulation of nonlinear localized waves including various types of solitons are among the paramount and advanced research field in nonlinear physics that generally includes three interdisciplinary directions: chaos, solitons and fractals. Particularly, instead of launching the critical collapses in two dimensional self-focusing systems and 3D supercritical one, novel ...
