设π是一个群,(H,σ)是一个余三角Hopfπ-余代数,在π-H-余模范畴中构造了一类广义Lie代数,并且得到了经典的Kegel定理。
Let π be a group and (H,σ) a cotriangular Hopf π-coalgebra. The difinitions of a class of generalized Lie algebras in the category of right π-comodules over H are introduced,and an analogue of the classical Kegel's theorem is obtained.
