Certain class of harmonic starlike functions with some missing coefficients.
The present investigation deals with a new subclass of alpha-convex bi-univalent functions in the unit disc defined with -derivative operator. Bounds for the first two coefficients and Fekete-Szegö inequality are established for this class. Many known results follow as consequences of the results derived here.
We define certain classes of functions associated with functions of bounded variation. Some characterizations of those classes are given.
In the paper we define classes of meromorphic multivalent functions with Montel’s normalization. We investigate the coefficients estimates, distortion properties, the radius of starlikeness, subordination theorems and partial sums for the defined classes of functions. Some remarks depicting consequences of the main results are also mentioned.
