In this paper, we analyze the harmonic curvature conditions of AW(k)-type (1 ≤ k ≤ 3) semi-real quaternionic curves and semi-real quaternionic Bertrand curves with k ≠ 0 and r ≠ 0 in E31 and we give some theorems and results on these curves.

For α(0 ≤ α < 1), η(0 ≤ η ≤ 1), β(0 < β ≤ 1), let Hm λ,μ(α; β, η) be the class of normalised functions defined in the unit disk μ by where Dm λ,μ is a linear multiplier differential operator and g ε Pm λ,μ(α; β, η) the class of normalized functions defined in the unit disk μ by For f ε Hm λ,μ(α; β, η) and given by f(z) = z +a2z2 +a3z3 +..., a sharp upper bound is obtained for {Pipe}a3-ξa22{Pipe} when A2ξ ≥ A21 where A1 and A2 are given below.
