Abstract
In the present paper, we introduce and study two new subclasses of the
function class Σm consisting of analytic and m-fold symmetric bi-univalent functions in
the open unit disk U. We establish upper bounds for the initial coefficients |am+1| and
|a2m+1| for functions in these subclasses. Certain special cases are also indicated.
