A note on the center of the queer super Yangian
Hao Chang, Hongmei Hu
We investigate two families of central elements of the queer super Yangian , arising from the constructions of Poletaeva-Serganova and from Nazarov's quant…
Shuffle algebra realizations for modular Yangians
Hao Chang, Hongmei Hu, Yue Hu
We study the shuffle algebra realization of positive modular Yangians of classical type over an algebraically closed field of characteristic . We show that, unlike in characte…
Super Yangians in characteristic
Hao Chang, Hongmei Hu
We define the super Yangian over a field $\mathbbm{k}$ of characteristic , and show that the super Yangian is a deformation of the super universal enveloping…
Modular orthogonal Yangians
Hao Chang, Hongmei Hu
We study the (extended) orthogonal Yangians associated to the Lie algebras types and over a field of positive characteristic. We define the -center for the Yangians and…
The center of modular shifted Yangians and parabolic generators
Hao Chang, Hongmei Hu
This paper is devoted to the study of the shifted Yangian associated to the general linear Lie algebra over a field of positive characteristic. We obtain…
The center of the modular super Yangian
Hao Chang, Hongmei Hu
The present paper is devoted to studying the super Yangian associated to the general linear Lie superalgebra over a field of positive characteristic…
