比较了弦场论顶点的各种分解和去压缩方法,分析了它们之间的关系。我们制定公理的八边形,并显示它如何可以被粘复制的解压缩PP-波SFT顶点,这反过来又可以被粘恢复精确的有限体积PP-波诺依曼系数。胶合是通过对多个包装校正进行重新排序来执行的。我们观察到重要的非平凡的贡献,在多个包装的水平,这是至关重要的,以获得准确的结果。
We compare various ways of decomposing and decompactifying the string field theory vertex and analyze the relations between them. We formulate axioms for the octagon and show how it can be glued to reproduce the decompactified pp-wave SFT vertex which in turn can be glued to recover the exact finite volume pp-wave Neumann coefficients. The gluing is performed by resumming multiple wrapping corrections. We observe important nontrivial contributions at the multiple wrapping level which are crucial for obtaining the exact results.
