A Perverse Sheaf Approach Toward a Cohomology Theory for String Theory
arXiv:0704.3298
Abstract
We present the construction and properties of a self-dual perverse sheaf S_0 whose cohomology fulfills some of the requirements of String theory as outlined by T. Hubsch in hep-th/9612075. The construction of this S_0 utilizes techniques that follow from MacPherson-Vilonen (Inv. Math. vol. 84, pp. 403-435, 1986). Finally, we will discuss its properties as they relate to String theory.
