$L^2$ Solutions for Cubic NLS Equation with Higher Order Fractional Elliptic/Hyperbolic Operators on Cylinder

Sala P3.10, Instituto Superior Técnico (com transmissão via Zoom)

Por Adán Corcho (Universidad de Córdoba).

In this work we consider the initial value problem for the cubic Schrödinger equation, posed on cylinder $\mathbb{R}\times \mathbb{T}$, with fractional derivatives in the periodic direction. The spatial operator includes elliptic and hyperbolic regimes. We prove $L^2$ global well-posedness results in the case of higher order derivatives in the periodic direction by proving a $L^4\times L^2$ Strichartz inequality.

Further, these results remain valid on the euclidean environment $\mathbb{R}^2$, so well-posedness in $L^2$ are also achieved in this case.

Our proof in the elliptic/hyperbolic case does not work for small order derivatives in the periodic direction.

The Lisbon Webinar in Analysis in Differential Equations is a joint iniciative of CAMGSD, CMAFcIO and GFM, three research centers of the University of Lisbon. It is aimed at filling the absence of face-to-face seminars and wishes to be a meeting point of mathematicians working in the field.
