本文构造了半对称空间上Green-Schwarz σ-模型的保积边界条件。边界条件表示为胶合条件的平坦连接，使用对合度量保持自同构。我们表明，边界条件保持一半的时空超对称性和一组无限的保守电荷。我们找到了AdS 5 × S5和$ { 联系我们 ext{S}}_4} imes mathbb{C}{{ ext{P}}^3} $个背景。
We construct integrability preserving boundary conditions for Green-Schwarz sigma-models on semi-symmetric spaces. The boundary conditions are expressed as gluing conditions of the flat-connection, using an involutive metric preserving automorphism. We show that the boundary conditions preserve half of the space-time supersymmetry and an infinite set of conserved charges. We find integrable D-brane configurations for AdS5 × S5 and $ { ext{Ad}}{{ ext{S}}_4} imes mathbb{C}{{ ext{P}}^3} $ backgrounds.
