%0 Journal Article %T Instability of Ginzburg-Landau Vortices on Manifolds %A Ko-Shin Chen %J Mathematics %D 2011 %I arXiv %R 10.1017/S0308210511000795 %X We investigate two settings of Ginzburg-Landau posed on a manifold where vortices are unstable. The first is an instability result for critical points with vortices of the Ginzburg-Landau energy posed on a simply connected, compact, closed 2-manifold. The second is a vortex annihilation result for the Ginzburg-Landau heat flow posed on certain surfaces of revolution with boundary. %U http://arxiv.org/abs/1108.1949v1
