Magneto-static vortices in two-dimensional Abelian gauge theories. (English) Zbl 1181.35227

Summary: We study the existence of vortices of the Klein-Gordon-Maxwell equations in the two-dimensional case. In particular we find sufficient conditions for the existence of vortices in the magneto-static case, i.e. when the electric potential \(\phi= 0\). This result, due to the lack of suitable embedding theorems for the vector potential \({\mathbf A}\) is achieved with the help of a penalization method.
