Simple Modules and PI Structure of the Two-Parameter Quantized Algebra $U_{r,s}^{+}(B_2)$

Snehashis Mukherjee, Ritesh Kumar Pandey

We study the two-parameter quantized enveloping algebra $U_{r,s}^{+}(B_2)$ at roots of unity and investigate its structure and representations. We first show that when $r$ and $s$ ar…
