Özet
In this paper, we introduce and investigate a subclass of analytic and bi-univalent functions which both f(z) and f(-1)(z) are m-fold symmetric on the open unit disk. Furthermore, we find upper bounds for the initial coefficients |a(m+1)| and |a(2m+1)| for functions in this subclass. The results presented in this paper generalize and improve some recent works
