Title：Rotating vortex solutions to the Gross-Pitaevskii system on the two-sphere
Abstract：I will discuss a result giving the existence of rotating solutions to the Gross-Pitaevskii equation, posed on the two-sphere.These solutions possess vortices that for all time follow the vortex paths of known rotating solutions to the point-vortex problem on the two-sphere in a certain asymptotic regime. The approach is variational, based on minimization of the Ginzburg-Landau energy subject to a momentum constraint. Time permitting, I will also discuss the orbital stability of these solutions within a class of symmetric initial data. This is joint work with Michael Gelantalis.
