摘要：
The z -divided powers (depending on a parity) form the zcanonical basis for the split rank 1 zquantum group and they are a basic ingredient for zquantum groups of higher rank. We obtain closed formulae for the structure constants for multiplication of the z -divided powers. Closed formulae for the comultiplication of the z -divided powers are also obtained. These structure constants are integral and positive.(c) 2022 Elsevier Inc. All rights reserved.
