4D-Space-Time Geometry & Cosmological Constant
Journal Title: JOURNAL OF ADVANCES IN MATHEMATICS - Year 2014, Vol 7, Issue 1
Abstract
In this paper, 4-dimensional space-time geometry has been discussed. The smallness of the effective cosmological constant constitutes the most difficult problems involving cosmology. Recent observations of Type Ia supernovae and measurements of the cosmic microwave background suggest that the universe is in an accelerating expansion phase

APPROXIMATION OF FOURIER SERIES OF A FUNCTION OF LIPCHITZ CLASS BY PRODUCT MEANS
Lipchitz class of function had been introduced by McFadden[5}.Recently dealing with degree of approximation of Fourier series of a function of Lipchitz class Nigam[12] and Misra et al.[13] have established certain theore...
Investigation of Laplace-Stieltjes transform for the ergodic distribution of the semi-markov random process with positive tendency, negative jumps and delaying boundary at zero.
One of the important problems of stochastic processes theory is to define the Laplace-Stieltjes transform for the ergodic distribution of semi-markov random process. With this purpose, we will investigate the semi-markov...
The Hermite Hadamard Inequality on Hypercuboid
Given any a := (a1; a2,... ; an) and b := (b1; b2;... ; bn) in Rn. The n-fold convex function dened on [a; b], a; b 2 Rn with a < b is a convex function in each variable separately. In this work we prove an...
Some Properties of Certain subclass of Meromorphically Multivalent Functions Defined by Convolution and Integral Operator involving I-Function
In the present paper, we introduce a certain subclass of meromorphic functions . We obtain some results, like, Coefficient inequality, Modified Hadamard Product, Integral means and Inclusion properties for this class.
The q-Exponential Operator and Generalized Rogers-Szego Polynomials
This paper is mainly concerned with using q-exponential operator T(bDq) in proving the identities that involve the generalized Rogers-Szego polynomials rn(x,b) . We introduce some new roles of the q -exponenti...
