Transference theory for the trilinear restriction estimate and an application to the quadratic NLS in 3D
Ioan Bejenaru, Vitor Borges, Tiklung Chan
In this article we develop a theory for effectively transferring trilinear restriction estimates for the Schrödinger equation to functions in a more general resolution space adapte…

The -linear restriction estimate in with degenerate curvature
Ioan Bejenaru, Tiklung Chan
We revisit the -linear restriction estimate in proved by the first author in \cite{Be-6} and refine the result in the case when the curvature assumptions cont…

A new resolution space for nonlinear Schrödinger equations and applications
Ioan Bejenaru
Resolution spaces play a central role in constructing solutions for nonlinear partial differential equations. One of the main goals in the area of nonlinear dispersive PDEs has bee…
