本文通过将2g型双参数量子群嵌入量子环面，计算了其正部分的导数。我们还证明了这个代数的第一个Hochschild上同群是复场上的二维向量空间。
In this paper, we compute the derivations of the positive part of the two-parameter quantum group of type G 2 by embedding it into a quantum torus. We also show that the first Hochschild cohomology group of this algebra is a two-dimensional vector space over the complex field.
