On subclasses of bi-convex functions defined by Tremblay fractional derivative operator

Sevtap Sümer Eker, Bilal Şeker


We introduce and investigate new subclasses of analytic and bi-univalent functions defined by modified Tremblay operator in the open unit disk. Also we obtain upper bounds for the coefficients of functions belonging to these classes.
