In the present investigation, we introduce and investigate a new subclass of the function class ? of bi-univalent functions defined in the open unit disc. We find estimates on the coefficients |a2| and |a3| for functions in the function class S?(n, h... see more

In this investigation a new subclass of bi-univalent functions is established that is defined in the open unit disk ?={?? ? C: |??| < 1} and are endowed with the Salagean type q-difference operator. Then, Hankel inequalities for the new ... see more

In our present investigation, we use the Faber polynomial expansions to find upper bounds for the n-th (n > =4) coefficients of general subclass of analytic bi-univalent functions. In certain cases, our estimates improve someof those existing coefficie... see more

In the present paper, by using the Lp,q,n(x) functions, our methodology intertwine to yield the Theory of Geometric Functions and that of Special Functions, which are usually considered as very different fields. Thus, we aim at introducing a new class of ... see more

Hankel matrices are related to a wide range of disparate determinant computations and algorithms and some very attractive computational properties are allocated to them. Also, the Hankel determinants are crucial factors in the research of singularities an... see more

In this paper, we introduce and investigate a new subclass of bi-univalent functions S of complex order dened in the open unit disk, which are associated with hypergeometric functions and satisfying subordinate conditions. Furthermore, we nd estimate... see more

Making use of the Hankel determinant, in this work, we consider a general subclass of bi-univalent functions. Moreover, we investigate the bounds of initial coefficients of this class.

In the present investigation, we find estimates on the coefficients |a2| and |a3| for functions in the function class S_{S}(?,h). The results presented in this paper improve or generalize the recent work of Magesh and Yamini.

In this paper, we introduce and investigate two new subclasses of the functionclass\sigma of bi-univalent functions dened in the open unit disk, which are associated with thegeneralized Srivastava-Attiya operator, satisfying subordinate conditions. Furthe... see more
