“…In 2007, Ali et al [2] extended this result and determined the estimates on β for which the subordination 1 + βzp ′ (z)/p j (z) ≺ (1 + Dz)/(1 + Ez) (j = 0, 1, 2) implies the subordination p(z) ≺ (1 + Az)/(1 + Bz), where A, B, D, E ∈ [−1, 1]. In 2013, Omar and Halim [15] determined the condition on β in terms of complex number D and real E with −1 < E < 1 and |D| ≤ 1 such that 1+βzp ′ (z)/p j (z) ≺…”
