  • A Presentation of the Automorphism Group of the Two-Generator Free Metabelian and Nilpotent Group of Class c 
    Gupta, C.K.; Wan Lin (Український математичний журнал, 2002)
    We determine the structure of IA(G)/Inn(G) by giving a set of generators, and showing that IA(G)/Inn(G) is a free abelian group of rank (c − 2)(c + 3)/2. Here G = M₂, c = 〈 x, y〉, c ≥ 2, is the free metabelian nilpotent ...
  • Free products of finite groups acting on regular rooted trees 
    Gupta, C.K.; Gupta, N.D.; Oliynyk, A.S. (Algebra and Discrete Mathematics, 2007)
    Let finite number of finite groups be given. Let n be the largest order of their composition factors. We prove explicitly that the group of finite state automorphisms of rooted n-tree contains subgroups isomorphic to the ...
  • On 2-Symmetric Words in Nilpotent Groups 
    Gupta, C.K.; Holubowski, W. (Український математичний журнал, 2002)
    We find the nilpotency class of a group of 2-symmetric words for free nilpotent groups, free nilpotent metabelian groups, and free (nilpotent of class c)-by-Abelian groups.
