Aspects related to applications in the geometric function theory of q-calculus are presented
in this paper. The study concerns the investigation of certain q-analogue differential …

In this article, we use the concept of symmetric q-calculus and convolution in order to define
a symmetric q-differential operator for multivalent functions. This operator is an extension of …

In this article we explore several applications of q-calculus in geometric function theory.
Using the method of differential subordination, we obtain interesting univalence properties …

As a counterpart to best approximation in normed linear spaces, best coapproximation was
introduced by Franchetti and Furi. In this paper, we shall show that if M is a separable …

The purpose of this paper is to introduce and to discuss the concept of orthogonality in the
locally convex spaces, and obtaining some results on orthogonality in locally convex spaces …

As a counterpart to best approximation in normed linear spaces, best coapproximation was
introduced by Franchetti and Furi,[3], in 1972. If X is a Banach space, E (X) the Köthe …

The tools and techniques employed in abstract approximation theory are listed. Several
important applications stem out of the theory and will prove to be useful in mathematical …

The purpose of this paper is to introduce and discuss the concept of the maps which
preserve approximation. We show that if a operator on a normed space is an isometry then …

As a counterpart to best approximation in normed linear spaces, best coapproximation was
introduced by Franchetti and Furi. In this paper, we apply the above coapproximation, and …
