In the present paper, we consider the class A¯ of functions f(z) of the form f(z)=z+∑k=1∞a1+k3z1+k3 that are analytic in the open unit disc U. If a1+k3=0 for k≠3n(n=1,2,3,⋯), then f(z) is given by f(z)=z+∑k=2∞akzk. For such functions f(z

Let A¯ be the new general class of functions f(z) of the form f(z)=z+∑k=1∞a1+k2z1+k2 that are analytic in the open unit disc U. In the present paper, for f(z)∈A¯, we consider classes S∗¯(α), C¯(α) and R¯(α) and obtain some interesting

Let the class of functions of f(z) of the form f(z)=z+∑k=2∞akzk, which are denoted by A and called analytic functions in the open-unit disk. There are many interesting properties of the functions f(z) in the class A concerning the subordinations.

Let Σ be the class of functions f(z) of the form f(z)=1z+∑k=0∞akzk, which are analytic in the punctured disk. Using the differentiations and integrations, new operator Dnf(z) is introduced for f(z)∈Σ. The object of the present paper is to dis

As an application of the well-known Sălăgean differential operator, a new operator is introduced and, using this, a new class of functions Sn(α) is defined, which has the classes of starlike and convex functions of order α as special cases. Origi

Let $$T_n$$ be the class of functions $$f(z)=z+a_{n+1}z^{n+1}+a_{n+2}z^{n+2}+\ldots $$ that are analytic in the closed unit disc $$\mathbb {{\overline{U}}}.$$ With m different boundary points $$z_{s}, (s=1,2,\ldots , m),$$ we consider $$\alpha _{m}\i

In the present paper, new subclasses of bi-univalent functions of complex order associated with hypergeometric functions are introduced and coefficient estimates for functions in these classes are obtained. Several new (or known) consequences of the

In this paper, we introduce and investigate a new subclass of bi-prestarlike functions defined in the open unit disk, associated with Chebyshev Polynomials. Furthermore, we find estimates of first two coefficients of functions in these classes, makin
