Abstract

Let ℤ_p²⋊_ϕℤ_p be the semi-direct product of ℤ_p² and ℤ_p with respect to ϕ,
(ϕ is homomorphism from ℤ_p to automorphisms
group of ℤ_p²). In this work, the group Aut_C(ℤ_3²⋊_ϕℤ₃) of all central automorphisms
of ℤ_3²⋊_ϕℤ₃ is studied and we determine
the form of central automorphisms of ℤ_3²⋊_ϕℤ₃ . 

Keywords
