Cohomology ring of the BRST operator associated to the sum of two pure spinors
Published Web Locationhttps://arxiv.org/pdf/1305.0071.pdf
In the study of the Type II superstring, it is useful to consider the BRST complex associated to the sum of two pure spinors. The cohomology of this complex is an infinite-dimensional vector space. It is also a finite-dimensional algebra over the algebra of functions of a single pure spinor. In this paper we study the multiplicative structure.
