Abstract: | We study the self-dual Chern-Simons Higgs equation on a compact Riemann surface with the Neumann boundary condition. In the
previous paper, we show that the Chern-Simons Higgs equation with parameter λ > 0 has at least two solutions (u
λ
1, u
λ
2) for λ sufficiently large, which satisfy that u
λ
1 → −u
0 almost everywhere as λ → ∞, and that u
λ
2 → −∞ almost everywhere as λ → ∞, where u
0 is a (negative) Green function on M. In this paper, we study the asymptotic behavior of the solutions as λ → ∞, and prove that u
λ
2 − `(ul 2 )]\overline {u_\lambda ^2 } converges to a solution of the Kazdan-Warner equation if the geodesic curvature of the boundary ∂M is negative, or the geodesic curvature is nonpositive and the Gauss curvature is negative where the geodesic curvature is
zero. |
