Recently, Mittag-Leffler function acts as beneficial role in studies of univalent functions. In this paper, motivated by some recent works, two new subclasses of univalent functions involving q−Mittag-Leffler function are introduced. Also, convolution conditions and coefficient estimates for these classes are investigated. The obtained results are presented in comparison with the results in the literature.

Son zamanlarda, Mittag-Leffler fonksiyonu yalınkat fonksiyonlar ile ilgili çalışmalarda önemli rol oynamaktadır. Bu makalede, yapılan son çalışmaların ışığında q−Mittag-Leffler fonksiyonu ile tanımlı yalınkat fonksiyonların iki yeni alt sınıfı tanımlanmıştır. Bu sınıflar için konvolüsyon koşulları ve katsayı tahminleri araştırılmıştır. Elde edilen bulgular literatürde olan bulgularla karşılaştırılarak sunulmuştur.
