Abstract:

Let $H$ be a finite abelian group and $Dih(H)$ $=$ $\langle H, b | b^2 = 1 \ \& \ bhb^{-1} = h^{-1}; \ \forall h \in H \rangle$ be the generalized dihedral group of $H$. The aim of this paper is to compute the number of group homomorphisms between two generalized dihedral groups and a generalized dihedral group and an abelian group. One of these results generalized an earlier work by J. W. Johnson published in 2013.

Primary keywords:
