摘要:

该文对出现在 Born-Infeld 理论中的 Ablelian Higgs 模型所对应的 BPS 方程, 针对两类边界条件, 利用动态射击法证明了 BPS 方程两点边值问题解的存在唯一性, 最后给出了解在无穷远处的渐近估计.

关键词: Born-Infeld 理论, 阿贝尔 Higgs 模型, 畴壁解, 动态射击法, 存在唯一性, 渐近估计

Abstract:

In this note, we research the Abelian Higgs model subject to the Born-Infeld theory for which the BPS equations can be reduced to a quasi-linear differential equation. We show that the equation exists a unique solution under two interesting boundary conditions which realize the corresponding phase transition. The solution is constructed using a dynamical shooting method for which the correct shooting slope is unique. We also obtain the sharp asymptotic estimate for the solution at infinity.

Key words: Born-Infeld theory, Abelian Higgs model, domain wall, dynamical shooting method, existence and uniqueness, asymptotic estimates
