Abstract :
T h e iso clinism o f L i e algebra i s widely used i n the classification o f Lie algebra. This concept has a weaker structure than t h e concept o f the isomorphism. T h e iso clinism o f Lie algebra was first introduced by the Moneyhun and later it is generalized by others to n- iso clinism in Lie algebra, as well as, to the iso clinism in a pair of Lie algebra in the literature. In this paper, we study the n- isoclinism in Lie algebra and prove some of the features of the n- iso clinism in Lie algebra. For example, we prove that if L 1 and L 2 are two Lie algebras that the intersection of their centroid and F rattini algebra are zero, then, the iso clinism L 1 and L 2 are equivalent to their central factors.
