In this paper, we introduce the notion of degree to which a Q- fuzzy subset is a Q- fuzzy group by means of the implication operator of [0,1]. A Q-fuzzy subset A in a group G is a Q- fuzzy group if and only if its subgroup degree dg(A) = 1. Some properties of subgroup degree are investigated.

Modelling is an important part of any large scale decision making process in a system. There are large numbers of factors that affect the performance of the system. It is not possible for the human brain to keep track of the all the players in the system, their interactions and interrelationships at a time. Therefore, to get the solution of the complex theoretical problems, one resort to the techniques, which are simple to use. Also, these techniques should be capable to reproduce all the essential and important relationships of the reality. Mathematical modelling is one such basic technique. This paper presents a literature review of the work done by several researchers to study the problems faced by industries, using mathematical modelling; particularly in the field of Diffusion innovation, Inventory Control and Production function.

This paper serves as a platform to discuss and bring out the concept of kernel, separation axiom and continuity of ?gb+ and ?gb+ -closed sets, under the light of simple extension topological spaces.

The purpose of this paper is to find the value function for financial problem whose dynamic is described by non-deterministic differential equation.

In this paper we prove a unique common fixed point theorem in 2-metric space .the existence of fixed point for two weakly compatible maps into 2-metric space is established under new contractive condition of integral type by using another functions and

This paper proposes a new crossover for the shortage of genetic algorithm, which is called Same-position reverse Crossover, replaces the mutation operator in genetic algorithm for trust region method. Finally, proves convergence of algorithm. Numerical experiment shows that the new method is effective.

In this paper, we discuss the applicability of new integral transform called Elzaki transform method to solve few mixing problems of single tank which are comes under the category of applications of first order linear differential equations.

Mathematics has double characters including science and technology. What sort of technology the mathematics is? The direct research object of mathematics is mode, and the mode is the carrier of information, and the evolvement of mode is the process of information processing and information conversion. Therefore, mathematics is the technology of information processing and information conversion.

The main focus of this paper is to introduce the properties of some special types of compact spaces.

Primes are the building blocks of integer universe. Prime numbers plays a major role in number theory. This paper is a detailed survey on prime numbers.This describes different types of primes and some testing methods. In addition to that, we have constructed MATLAB programs using popular primality tests to determine a given positive integer is prime or not. Further, this concises the definitions regarding prime numbers, history of prime numbers, distribution of prime numbers, some mathematical occurrences and open questions concerning prime numbers. Moreover, the usage of primes in nature and in the real life has been considered.
