定义复数域C上的Laurent多项式代数C[t,t^-1]的(r,s)-微分算子 r,s.给出该微分算子及{t^±1)生成的结合代数即(r,s)-微分算子代数的-组基,并在此基础上研究了(r,s)-微分算子代数的导子代数及其非平凡二上圈.
This paper defined the (r,s)-differential operator of the algebra of Laurent poly- nomials over the complex numbers field. Let 79r,8 be the associative algebra generated by {t^±1} and the (r, s)-differential operator, which is called (r, s)-differential operators algebra. In this paper, the derivation algebra of Dr,s and its Lie algebra Dr,s^- were described and all the non-trivial 2-cocycles were determined.
