Abstract : In this paper, when G is a connected and simply connected nilpotent Lie group of dimension less than or equal to four, we study the uniform lattices Γ of G up to isomorphism and then we study the structure of the automorphism group Aut(Γ) of Γ in the view point of splitting as a natural extension.
Keywords : automorphism, nilpotent Lie group, splitting, uniform lattice
