Bilinear estimates associated to the Schrödinger equation with a nonelliptic principal part

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/144518We discuss bilinear estimates of tempered distributions in the Fourier restriction spaces for the two-dimensional Schödinger equation whose principal part is the d'Alembertian. We prove that the bilinear estimates hold if and only if the tempered distributions are functions.final versionClassical Analysis and ODEsAnalysis of PDEs42B35 (Primary) 35B65, 35Q55 (Secondary)Bilinear estimates associated to the Schrödinger equation with a nonelliptic principal parttext
