    • Cat1-polygroups and pullback cat1-polygroups 

      Davvaz, Bijan; Alp, Murat (Iranian Mathematical Society, 2014)
      In this paper, we give the notions of crossed polymodule and cat1-polygroup as a generalization of Loday's definition. Then, we define the pullback cat1-polygroup and we obtain some results in this respect. Specially, we ...
