我们在之前的工作中表明，对于adss的均匀Yang-Baxter （YB）变形，开弦度规和耦合以及闭弦密度保持不变。在这项工作中，除了将这些结果扩展到与修改的CYBE或变形相关的变形之外，我们还将Page形式识别为RR字段的开放字符串对应项，并逐例证明非零Page形式在YB变形下保持不变。我们给出了广义超引力的消灭向量的物理意义，并证明了对于所有YB变形：(1)i表现为质心运动在探索背景的d膜的世界体积上的电流，(2)i等于非对易性参数的散度，(3)i表现出“全息”行为，其中i的径向分量在AdS边界消失，(4)在纯旋量形式中，i与BRST上同调中的某个状态有关。
We showed in previous work that for homogeneous Yang–Baxter (YB) deformations of AdSSthe open string metric and coupling and as a result the closed string densityremain undeformed. In this work, in addition to extending these results to the deformation associated with the modified CYBE or-deformation, we identify the Page forms as the open string counterpart for RR fields and demonstrate case by case that the non-zero Page forms remain invariant under YB deformations. We give a physical meaning to the Killing vectorIof generalized supergravity and show for all YB deformations: (1)Iappears as a current for the center of mass motion on the worldvolume of a D-brane probing the background, (2)Iis equal to the divergence of the noncommutativity parameter, (3)Iexhibits “holographic” behavior where the radial component ofIvanishes at the AdS boundary and (4) in pure spinor formalismIis related to a certain state in the BRST cohomology.
