This article addresses the problem of coefficient bounds for certain subclasses of normalized holomorphic and m-fold symmetric bi-univalent functions associated with λ-pseudo-starlike and λ-pseudo-convex structures in the open unit disk Ữ. Upper estimates for the initial Taylor–Maclaurin coefficients are derived for two newly considered families. Several previously known results follow as particular instances of the obtained estimates.
