Kontsevich–Witten hypergeometricity conjecture. The Kontsevich–Witten tau-function is also a hypergeometric solution of the BKP hierarchy.

Let $\operatorname{DP}$ be the set of strict partitions, and let a hypergeometric BKP tau-function be expressed as … with $r_\lambda=e^{\sum_{j=1}^{\ell(\lambda)}\xi(\lambda_j)}$.…
