论文摘要
如果时空是一个开放的流形，则弦理论的有效作用具有批量和边界项。最近，通过限制有效的动作，在量规变换和弦划分转换下，已重现了$α'$的领先顺序及其相应边界作用的弦理论的已知经典有效动作。在本文中，我们使用此想法来找到O-Plane的经典有效作用及其在II型超音型理论中的相应边界项，以$α'^2 $和NS-NS耦合。我们发现这些约束将批量操作及其相应的边界项固定到一个总体因素。它们还会在边界作用中产生三个多重组，即它们的系数独立于弦双重性下的散装耦合。
The effective action of string theory has both bulk and boundary terms if the spacetime is an open manifold. Recently, the known classical effective action of string theory at the leading order of $α'$ and its corresponding boundary action have been reproduced by constraining the effective actions to be invariant under gauge transformations and under string duality transformations. In this paper, we use this idea to find the classical effective action of the O-plane and its corresponding boundary terms in type II superstring theories at order $α'^2$ and for NS-NS couplings. We find that these constraints fix the bulk action and its corresponding boundary terms up to one overall factor. They also produce three multiplets in the boundary action that their coefficients are independent of the bulk couplings under the string dualities.
