Meromorphically Starlike Functions at Infinity

, 2020
In this letter, we introduce meromorphically starlike functions by using a particular class of analytic functions that present authors applied in 2012 [cf.[1]]. These functions map the punctured unit disk into a starlike domain at infinity.

Certain classes of starlike functions. [PDF]

Michigan Mathematical Journal, 1985
The author introduces a one parameter family of starlike mappings in the unit disk by proving that if f(z) is analytic in \(| z| 0. \] The proof is based on an extended version of the author's lemma in Trans. Am. Math. Soc. 76, 254-274 (1954; Zbl 0057.311). Some applications are also given.
