Abstract:  
The purpose of the present paper is to introduce and investigate two new subclasses π’¦π›΄π‘š(πœ†,𝛾;𝛼) and 𝒦∗π›΄π‘š(πœ†,𝛾;𝛽) of π›΄π‘š consisting of analytic and π‘š-fold symmetric bi-univalent functions defined in the open unit disk π‘ˆ. We obtain upper bounds for the coefficients |π‘Žπ‘š+1| and |π‘Žπ‘š| for functions belonging to these subclasses. Many of the well-known and new results are shown to follow as special cases of our results.
