Coefficient bounds for certain subclasses of bi-univalent function
Summary: We introduce two new subclasses of the function class \(\Sigma\) of bi-univalent functions defined in the open unit disc. Furthermore, we find estimates on the coefficients \(|a_2|\) and \(|a_3|\) for functions in these new subclasses. Also consequences of the results are pointed out.
