Certain Conditions for Starlikeness of Analytic Functions of Koebe Type
For 𝛼≥0, 𝜆>0, we consider the 𝑀(𝛼,𝜆)𝑏 of normalized analytic 𝛼−𝜆 convex functions defined in the open unit disc 𝕌. In this paper, we investigate the class 𝑀(𝛼,𝜆)𝑏, that is, Re{(𝑧𝑓𝑏(𝑧)/𝑓𝑏(𝑧))[1−𝛼+𝛼(1−𝜆)(𝑧𝑓𝑏(𝑧)/𝑓𝑏(𝑧))+𝛼𝜆(1+(𝑧𝑓𝑏(𝑧)/𝑓𝑏(𝑧)))]}>0, with 𝑓𝑏 is Koebe type, that is, 𝑓𝑏(𝑧)∶=𝑧/(1−𝑧𝑛)...
