Abstract
LetΩ ⊂ ℝ2 be a smooth bounded simply connected domain. Consider the functional
on the classH 1g ={u εH 1(Ω; ℂ);u=g on ∂Ω} whereg:∂Ω∂ → ℂ is a prescribed smooth map with ¦g¦=1 on ∂Ω∂ and deg(g, ∂Ω)=0. Let uu ε be a minimizer for Eε onH 1g . We prove that uε → u0 in\(C^{1,\alpha } (\bar \Omega )\) as ε → 0, where u0 is identified. Moreover\(\left\| {u_\varepsilon - u_0 } \right\|_{L^\infty } \leqslant C\varepsilon ^2 \).
