    Peiffer commutators by using GAP package
    (Assoc Sci Res, 1998) Mutlu Ali
    We describe Peiffer commutators within the Moore complex NG of a simplicial group G. The calculation of the Peiffer commutators is made by using GAP program.

    Free 2-crossed complexes of simplicial algebras
    (Assoc Sci Res, 2000) Mutlu Ali
    Using free simplicial algebras, it is shown that a free or totally free 2-crossed module can be constructed on suitable construction data in [2]. In this paper 2-crossed complexes and freeness conditions for 2-crossed complexes are introduced and similar freeness results for these are discussed.

    Join for (augmented) simplicial group
    (Assoc Sci Res, 2000) Mutlu Ali
    We introduced a notion of join for (augmented) simplicial groups generalising the classical join of geometric simplicial complexes. The definition comes naturally the ordinal sum on the base simplicial category Δ.
