A class of analytic functions related to convexity and functions with bounded turning. (English) Zbl 1484.30033

Summary: In this paper, we define a new subclass \(k-\mathcal{Q} (\alpha)\) of analytic functions, which generalizes the class of \(k\)-uniformly convex functions. Various interesting relationships between \(k-\mathcal{Q} (\alpha)\) and the class \(\mathcal{B}(\delta)\) of functions with bounded turning are derived.
