标题： BPS Wall in N=2 SUSY Nonlinear Sigma Model with Eguchi-Hanson Manifold

摘要： 带有Eguchi-Hanson目标流形的N=2超对称非线性Sigma模型以明显的超对称方式得到了BPS墙解。 该模型通过质量超凯勒商方法在N=1超场和N=2超场（谐波超空间）中构建。 我们用简单的术语描述了该模型，并给出了各种参数化之间的关系，这些参数化对于描述模型和解很有用。 更多细节可以在我们的先前论文[hep-th/0211103]中找到。 本文是献给 七十大寿的广岛浩教授。 显示英文摘要

摘要： BPS wall solutions are obtained for N=2 supersymmetric nonlinear sigma model with Eguchi-Hanson target manifold in a manifestly supersymmetric manner. The model is constructed by a massive hyper-Kahler quotient method both in the N=1 superfield and in the N=2 superfield (harmonic superspace). We describe the model in simple terms and give relations between various parameterizations which are useful to describe the model and the solution. Some more details can be found in our previous paper [hep-th/0211103]. This article is dedicated to Professor Hiroshi Ezawa on the occasion of his seventieth birthday.
