Abstract
In this paper we generalize several results of normal lattice in terms of n ideals. We prove that the lattice of finitely generated n-ideals F-n(L) is normal if and only if each prime n-ideal contains a unique minimal prime n-ideal. It is also shown that F-n(L) is normal if and only if (< x >(n) boolean AND < y >(n))*= (x)(n)* V < y >(n), for all x, y is an element of L.
