Fractional Calculus Operators Associated with a Subclass of Uniformly Convex Functions

Making use of fractional calculus operator, we define a new subclass of uniformly convex functions with negative coefficients. Characterization property, extreme points, distortion bounds, the results on Integral transform and sharp integral means inequalities for the function class are determined.

Some Properties of Unisrially Embedding of Subgroups of P-Groups

This paper focuses attention on the study of the Question 3.1. of [1] and it can be considered as a continuation of the previously mentioned paper. A subgroup H of a p-group G is n-uniserial if for each i = 1, ..., n, there is a unique subgroup Ki such that H  Ki and |Ki : H| = pi.

Homotopy Analysis Method for Delay-Integro-Differential Equations

In this paper, we implement the homotopy analysis method to solve delay-integro-differential equations. The convergence of the method is investigated. In the end, numerical experiments are presented to illustrate the computational effectiveness of the method.

An Alternative Proof of the Friendship Theorem

Several proofs of the friendship theorem are known. In this paper an alternative proof will be given for friendship theorem. The goal of this paper is to provide a proof which is perhaps more combinatorial.

A Prey-Predator Model with cover for the Prey and An Alternative Food for the Predator and Constant Harvesting of Both the Species

The present paper is devoted to an analytical investigation of a two species preypredator model. Predator is provided with a limited resource of food in addition to the prey and a cover to prey proportionate to its population to get protection from the predator. Both the prey and predator are harvested at a constant rate.
