Abstract: This given note is a brief introduction to a new branch of Mathematics which comes under the category Exponentiation. Which deals with the study of base (of an exponential expression) and its split terms, explains the relation between the split terms, gives an extension for exponentiations (like Square, Cube etc.). That we can call as "Exponential Base Splitting Expressions-Extensions" simply abbreviated as "Exbaspex . The main objective of this branch is to provide a suitable extension for all exponential expressions and thereby increasing the possibilities and futher applications of exponentiations.

Abstract: In this paper, an existence result for a nonlinear fourth order random differential equation is proved under Carathéodory condition. Two existence result for extremal random solutions are also proved for Carathéodory as well as discontinuous cases of nonlinearity involved in the equation. Our investigation are placed in the Banach space of continuous real valued function on closed and bounded interval of the real line together with an application of the random version of the Leray-Schauder Principle.

Abstract:In this paper an interesting and famous realistic Lorenz's nonlinear problem is discussed using the Adomian Decomposition Method (ADM). The results (approximate solutions) obtained very accurate using classical Runge-Kutta (RK) method, single-term Haar Wavelet series [8] and ADM methods are compared with the ODE45 in Matlab. It is found that the solution obtained using ADM is closer to the ODE45 in Matlab. The high accuracy and the wide applicability of ADM approach will be demonstrated with numerical example. Solution graphs for discrete exact solutions are presented in a graphical form to show the efficiency of the ADM. The results obtained show that ADM is more useful for solving Lorenz's nonlinear problems and the solution can be obtained for any length of time.

Abstract:An antimagic labeling of a digraph D with p vertices and q arcs is a bijection f from the set of all arcs to the set of positive integers f:{1, 2, 3, …,q} such that all the p oriented vertex weights are distinct, where an oriented vertex weight is the sum of the labels of all arcs entering that vertex minus the sum of the labels of all arcs leaving it. A digraph D is called antimagic if it admits an antimagic סּlabeling. In this paper we investigate the existence of antimagic labelings of symmetric digraphs using Skolem sequences.

Keywords: antimagic labeling, symmetric digraph. 2010 Mathematics Subject Classification: 05C78.

Abstract:In this paper, He's Homotopy Perturbation Method (HHPM) is used to study the linear first order fuzzy differential equations (FDE). The results obtained using He's Homotopy Perturbation Method and the methods taken from the literature [9] were compared with the exact solutions of the linear first order fuzzy differential equations. It is found that the solution obtained using the He's Homotopy Perturbation Method is closer to the exact solutions of the linear first order fuzzy differential equations. Error graphs for discrete and exact solutions are presented in a graphical form to highlight the efficiency of this method.

Abstract: The unsteady free convective viscous incompressible flow of an electrically conducting fluid, under uniform magnetic field, through porous medium near vertical insulated wall with variable suction in slip flow has been investigated. The governing equation in non-dimensional form is solved with the help of Perturbation technique. An approximated solution for velocity, skin friction, temperature and Nusselt number are obtained. The effects of various non-dimensional parameters on velocity profile, skin friction and Nusselt number are shown graphically.
