Indian scientist Amal Kumar Raychaudhuri established ‘Raychaudhuri equation’ in 1955 to describe gravitational focusing properties in cosmology. This equation is extensively used in general relativity, quantum field theory, string theory and the theory of relativistic membranes. This paper...

We consider a situation where the relatively ‘poor’ are concerned about their relative income status with respect to a relevant reference group. Such a concern is explicitly introduced in a utility function to study the consumption and saving behavior of the poor in terms of a static and...

An exact solution of Einstein equation is easier than actual solution. The Schwarzschild metric is established on the basis of Einstein’s exact solution and it is also a static and stationary solution. The Schwarzschild solution expresses the geometry of a spherically symmetric massive...

This study aims to investigate the food, agriculture and economic situation of Bangladesh in some details. Although it faces various problems in economic progress since the independent in 1971, in the last forty years the increase of food production, economic development and poverty reduction of...

The aim of the study is to describe the general upper limit of the age of the universe with the help of different cosmological models of the universe. Here homogeneous and isotropic assumptions of the observed universe are not strictly followed to calculate the present age of the universe....

This paper discusses the global food price hike and the effects of it among the poor of developing countries. Increase of food price became severe during 2007 and 2008, which was high in the last fifty years and more than half of the populations of the world affected due to this price hike....

The impact of education on earnings and thus on poverty works largely through labour market. Along with some other socio economic factors, education does play a crucial role to alleviate poverty. Better educated people has greater probability of being employed, are economically more productive...

The Friedmann, Robertson-Walker universe is based on the assumption that the universe is exactly homogeneous and isotropic. This model expresses that there is an all encompassing big bang singularity in the past as the origin from which the universe emerges in a very hot phase and continues its...
