Some criteria for starlikeness and strongly starlikeness. (English) Zbl 1094.30021
The authors discuss on certain sufficient conditions for starlikeness and strongly starlikeness of analytic functions in the unit disk. Their results generalise and refine known results of J.-L. Li and S. Owa [Indian J. Pure Math. 33, 313–318 (2002; Zbl 0998.30010), Georgian Math. J. 5, 361–366 (1998; Zbl 0924.30008)] and of C. Ramesha et.al [Chin. J. Math. 23, 167–171 (1995; Zbl 0834.30010)]. Further some other new results are obtained.
