• Resumen

  • The goal of the paper is to introduce a new set of tools for the study of discrete and continuous β-corners processes. In the continuous setting, our work provides a multilevel extension of the loop equations (also called Schwinger–Dyson equations) for β-log gases obtained by Borot and Guionnet in (Commun. Math. Phys. 317, 447– 483, 2013). In the discrete setting, our work provides a multi-level extension of the loop equations (also called Nekrasov equations) for discrete β-ensembles obtained by Borodin, Gorin and Guionnet in (Publications mathématiques de l’IHÉS 125, 1–78, 2017).
