Solving the 4NLS with White Noise Initial Data

Solving the 4NLS with White Noise Initial Data

Explore a lecture on solving the 4NLS (fourth-order nonlinear Schrödinger equation) with white noise initial data. Delve into the connection between white noise and partial differential equations, focusing on Hamiltonian PDEs. Examine the general globalization argument and its application to global solutions. Investigate the proof, limits, and complexity of the problem, including invariance properties and smooth solutions. Analyze the limit equation, compare more precise solutions, and study the Borg approach. Gain insights from speaker Nikolay Tzvetkov of the University of Cergy-Pontoise, France, in this comprehensive talk from the School and Workshop on Mixing and Control.
