Moreover, we aim to present a new subclass C-Sigma m (tau; beta) related to m-fold symmetric bi-univalent functions in the open unit disk Theta ={z is an element of C: |z| < 1}. Finally, an estimate related to the Hankel determinant for functions in C-Sigma m (tau; beta) are given.eninfo:eu-repo/semantics/openAccessUnivalent functionCoefficient estimateHankel determinantArticle10.35378/gujs.9583092-s2.0-851506839683601Q234936WOS:000979511700023N/A
