Title: Growth of SO(9) Representations in type II String Theory

 

Abstract: Using a refined partition function, we study the growth of SO(9) super-representations as well as ordinary representations appearing in type II string theory. By finding an empirical rule for the SO(9) representation content at a given mass level, we compute the multiplicities of all representations up to level 226, and of individual representations up to level 501. We also derive asymptotic formulae for the growth of individual representations by integrating around the peaks of the refined partition function and making use of Rademacher sums.
