 Low-Regularity Global Solutions to Nonlinear Dispersive Equations by Terence Tao

Author-attributed proceedings notes, printed pp. 19 onward. The inspected PDF heading supplies the work title and author; no publication year is inferred from its URL. Introduction, printed pp. 20–21, develops Hamiltonian conservation, and later discussion distinguishes rigorous low-regularity solution constructions from formal invariants.
