Radius of univalence of certain class of analytic functions

Let A denote be the class of analytic functions in the unit disk D with the normalization f (0) = f'(0) - 1 = 0. For z/ f (z) ≠, 0 in D, consider Under a suitable condition on Ω we determine the radius of univalence of f whenever Uf (z) ∈ Ω or B(z) ∈ Ω for z ∈ D.
