Abstract

We consider two new subclasses S-Sigma m(alpha,lambda) and S-Sigma m (beta,lambda) of Sigma(m) consisting of analytic and m-fold symmetric biunivalent functions in the open unit dis U. Furthermore, we establish bounds for the coefficients for these subclasses and several related classes are also considered and connections to earlier known results are made.
