Abstract:
The Dirichlet Boundary Condition specifies the value of a vector field at the boundary of a domain. In mathematical terms, it sets the value of the field directly at the boundary points, ensuring that the solution is fixed at those locations.

Abstract:
In this paper we have investigated cylindrically model in presence of electromagnetic field. Taking a suitable metric we have also found and discussed several physical and geometric properties e.g., pressure, density, scalar of expansion and shear tensor.

Abstract:
J. C. Kelley introduced the concept of bitopoloical spaces which are being discussed with suitable examples. We discuss here the concepts of pairwise continuous mapping, pairwise open mapping and pairwise homeomorphism of bitopological spaces to distinguish each from other. We analyse comparative merits and demerits different types of classifications of bitopological space.

Abstract:
The paper presents an investigation on relativistic red shift and Newtonian analogue of force for a cylindrically symmetric cosmological model which is derived for a perfect fluid with an electromagnetic field. Here we have shown that the force terms Ri and Si both are null force vectors and R4 and S4 have no Newtonian analogues. We have also found these terms in absence of electromagnetic field.

Abstract:
This paper presents mathematical model for flow of blood by application of Poiseuille law. Infact blood is carried from the heart to several parts of the body through a system of elastic tuber e.g. the arteries, capillaries and veins and eventually returned to the heart without leaving the system.

Abstract:
Generalized derivations form an important extension of classical derivations in ring theory, broadening the scope of algebraic mappings that preserve or reflect ring structure.

Abstract:
The study of fixed-point theorems for a map satisfying a contractive condition that did not require continuity at each point was initiated by Kannan [1] in 1968. This paper was a genesis for a multitude of fixed-point papers over the next two decades. Subsequently, several authors established fixed point theorems for a pair of maps.
