Abstract: DOI: 10.24193/subbmath.2020.1.04 Published Online: 2020-03-06 Published Print: 2020-03-30 pp. 47-55 VIEW PDF: FULL PDF ABSTRACT: In the present paper, we introduce new subclasses of the function class $sum$ of bi-univalent functions by using multiplier transformation. Furthermore, we obtain estimates on the coefficients $|a_2|, |a_3|~ ext{and}~|a_4|$ for functions of this class. Relevant connections of the results presented here with various well-known results are briefly indicated. Key words: Analytic, univalent, Bi-univalent functions, Multiplier transformation. |
