本文研究了变形背景下的单尖点极小曲面。尖点由两条任意角度的半直线组成，并在变形曲面中指定的曲面上实现。附着在这个尖点上的经典弦解被认为是Drukker和Forini [J. High Energy Phys.1106，131（2011）[arXiv：1105.5144 [hep-th]]在未变形情况下研究的构型的推广。通过取一个反平行线极限，用一定的减法方案导出了形变情况下的夸克-反夸克势。由此产生的潜力成为线性在短距离与有限的变形参数。特别地，非对易规范理论的引力对偶的线性行为可以被再现为一个特殊的标度极限。最后研究了势的近直线极限。
We study minimal surfaces with a single cusp in a-deformedbackground. The cusp is composed of two half-lines with an arbitrary angle and is realized on a surface specified in the deformed. The classical string solutions attached to this cusp are regarded as a generalization of configurations studied by Drukker and Forini [J. High Energy Phys.1106, 131 (2011) [arXiv:1105.5144 [hep-th]]] in the undeformed case. By taking an antiparallel-lines limit, a quark–antiquark potential for the-deformed case is derived with a certain subtraction scheme. The resulting potential becomes linear at short distances with a finite deformation parameter. In particular, the linear behavior for the gravity dual of noncommutative gauge theories can be reproduced as a special scaling limit. Finally we study the near straight-line limit of the potential.
