Existence of abelian BPS vortices on surfaces with Neumann boundary conditions

Abstract

Existence of abelian BPS vortices on a manifold with boundary satisfying Neumann boundary conditions is proved. Numeric solutions are constructed on the Euclidean disk, and the L^2-metric of the moduli space of one vortex located at the interior of a rotationally symmetry disk is studied. The results presented extend previous work of Manton and Zhao on quotients of surfaces that admit a reflection.
