Higher genus Siegel forms and multi-center black holes in N=4 supersymmetric string theory
Frederik Denef, Shamit Kachru, Zimo Sun +1
We conjecture that the Fourier coefficients of a degree three Siegel form, , count the degeneracy of three-center BPS bound states in type II string theory compact…
Black Holes and Hurwitz Class Numbers
Shamit Kachru, Arnav Tripathy
We define a natural counting function for BPS black holes in compactification of type II string theory, and observe that it is given by a weight 3/2 mock modular fo…
The hidden symmetry of the heterotic string
Shamit Kachru, Arnav Tripathy
We propose that Borcherds' Fake Monster Lie algebra is a broken symmetry of heterotic string theory compactified on . As evidence, we study the fully flavored count…
The symmetric power and étale realisation functors commute
Arnav Tripathy
We show that under mild hypotheses on a proper algebraic space , the functors of taking its symmetric powers and its étale realisation commute up to weak equivalence. We conclud…
