THE SHARP UPPER BOUND FOR RE(A 3-λA 2) IN U' α

In this note we determine the exact value of max Re(A 3 — λA 2), λ ∈ R, within the linearly invariant family U' α introduced by V. V. Starkov in [4]. For λ = 0 the sharp estimate for |A 3| follows. If α = 1 the corresponding result is valid for convex univalent functions in the unit disk....
