一类广义Heisenberg-Virasoro代数的导子

Derivations of a Class of Generalized Heisenberg-Virasoro Algebras

主要研究了一类非有限分次的广义Heisenberg-Virasoro代数HV,并给出了HV导子的具体结构.为了计算HV的导子Der HV,可以把它分解成内导子adHV和阶为零次的导子(Der HV)_0之和.

We study a class of not-finitely graded Lie algebras related to generalized Heisenberg-Virasoro algebras HV, and we determine the concrete structures of the derivations of HV. To compute the derivations Der HV of HV, we can decompose them into a sum of the inner derivations ad HV and the derivations （Der HV）o whose degree is zero.
