IIB型超引力中鬼数为3的顶点算符

Vertex operators of ghost number three in Type IIB supergravity

Andrei Mikhailov

摘要:

研究了平坦空间中IIB型纯旋量超弦的无质量BRST复形的上同调。特别是,我们发现,在鬼数3的上同调是非平凡的,并在相同的表示的超对称代数的线性化的经典超引力方程的解决方案,变换。模某些有限维空间,鬼数3上同调与鬼数2上同调相同。我们还评论了朴素上同调和半相对上同调之间的区别,以及b-鬼的作用。

英文摘要:

We study the cohomology of the massless BRST complex of the Type IIB pure spinor superstring in flat space. In particular, we find that the cohomology at the ghost number three is nontrivial and transforms in the same representation of the supersymmetry algebra as the solutions of the linearized classical supergravity equations. Modulo some finite dimensional spaces, the ghost number three cohomology is the same as the ghost number two cohomology. We also comment on the difference between the naive and semi-relative cohomology, and the role of b-ghost.
