Abstract
In this paper we consider a class of λ-pseudo bi-starlike functions defined by subordination and determine the upper bounds for the first two coefficients of m-fold symmetric functions in this class. We also determine upper bounds for the Fekete–Szegö coefficients of such m-fold symmetric functions. Our findings for certain cases improve some of the previously published results. © 2018, Springer Nature Switzerland AG.
