Title: A priori estimates for a critical Schrodinger-Newton equation Author: Marcelo M. Disconzi (Vanderbilt Univ., Nashville, TN, USA) Abstract: Under natural energy and decay assumptions, we derive a priori estimates for solutions of a Schrodinger-Newton type of equation with critical exponent. On the one hand, such an equation generalizes the traditional Schrodinger-Newton and Choquard equations; while, on the other hand, it is naturally related to problems involving scalar curvature and conformal deformation of metrics.
