Minimality of degree-one Ginzburg-Landau vortex in the unit ball

Abstract :
In this talk, we will focus on the standard Ginzburg-Landau energy for N-dimensional maps defined in the unit ball that are equal to the identity on the boundary.
A special critical point is the so-called degree-one vortex map given by the identity map multiplied with a scalar radial profile. We will prove the minimality of this solution and also discuss about the uniqueness result.
