Modular orthogonal Yangians

Quantum Algebra 2025-06-03 v1 Representation Theory

Abstract

We study the (extended) orthogonal Yangians associated to the Lie algebras types BB and DD over a field of positive characteristic. We define the pp-center for the Yangians and obtain an explicit description of the center in terms of Drinfeld generators, showing that the center is generated by its Harish-Chandra center together with a large pp-center.
