On the center of two-parameter (v,t)-quantum groups
Published 25 Dec 2024 in math.QA | (2412.18970v1)
Abstract: This paper mainly considers the center of two-parameter quantum group U_{v,t} of finite type via an analogue of the Harish-Chandra homomorphism. Through combining the connection between one-parameter quantum group case and two-parameter quantum group case, we get the description of center in the sense of Harish-Chandra homomorphism.
