论文摘要
从文献中已经知道的解决方案开始，我们研究了字符串理论中非苏匹配，正张力域壁的反应引起的动力恢复。这可以例如成为I型的非BPS D8-BRANE或$ \ OVILLINE {D8}/O8 $ stack的非supermmetric Type IIA Erientifold的堆栈。通常出现的奇异性表明该背景的固有不一致或所需的合适缺陷，如Coobordism猜想所预测的那样。我们提供的证据表明，这种世界末日的$ 7 $ - 由一种新型的非各向异性解决方案明确描述了Dilaton-Gravity Motion方程。有趣的是，在形式上，该解决方案证明与非苏匹配域壁的初始溶液密切相关。
Starting from an already known solution in the literature, we study the dynamical cobordism induced by the backreaction of a non-supersymmetric, positive tension domain wall in string theory. This could e.g. be a non-BPS D8-brane of type I or a $\overline{D8}/O8$ stack of a non-supersymmetric type IIA orientifold. The singularities which typically appear indicate either an inherent inconsistency of this background or the required presence of a suitable defect, as predicted by the cobordism conjecture. We provide evidence that this end-of-the-world $7$-brane is explicitly described by a new kind of non-isotropic solution of the dilaton-gravity equations of motion. Intriguingly, on the formal level this solution turns out to be closely related to the initial solution for the non-supersymmetric domain wall.
