Jacobi Beta Ensemble and -Hurwitz Numbers

We express correlators of the Jacobi ensemble in terms of (a special case of) -Hurwitz numbers, a deformation of Hurwitz numbers recently introduced by Chapuy and Dołęga. The proof relies on Kadell's generalization of the Selberg integral. The Laguerre limit is also considered. All the relevan...

description We express correlators of the Jacobi ensemble in terms of (a special case of) -Hurwitz numbers, a deformation of Hurwitz numbers recently introduced by Chapuy and Dołęga. The proof relies on Kadell's generalization of the Selberg integral. The Laguerre limit is also considered. All the relevant -Hurwitz numbers are interpreted (following Bonzom, Chapuy, and Dołęga) in terms of colored monotone Hurwitz maps.

I am grateful to Dan Betea, Massimo Gisonni, and Tamara Grava for valuable conversations and to Valentin Bonzom, Guillaume Chapuy, and Maciej Dołęga for insightful and helpful correspondence. I would also like to thank the anonymous referees for their useful suggestions. This work is supported by the FCT grant 2022.07810.CEECIND.
