Cosmology in Flat Space-Time
Flat space-time has not heretofore been thought a suitable locus in which to construct model universes because of the presumed necessity of incorporating gravitation in such models and because of the historical lack of a theory of gravitation in flat spacetime. It is here shown that a Lorentz-invariant theory of gravitation can be formulated by incorporating in it the mass-energy relation. Such...
متن کاملFixed point theorem for non-self mappings and its applications in the modular space
In this paper, based on [A. Razani, V. Rako$check{c}$evi$acute{c}$ and Z. Goodarzi, Nonself mappings in modular spaces and common fixed point theorems, Cent. Eur. J. Math. 2 (2010) 357-366.] a fixed point theorem for non-self contraction mapping $T$ in the modular space $X_rho$ is presented. Moreover, we study a new version of Krasnoseleskii's fixed point theorem for $S+T$, where $T$ is a cont...

متن کاملRe-Examination of Globally Flat Space-Time
In the following, we offer a novel approach to modeling the observed effects currently attributed to the theoretical concepts of "dark energy," "dark matter," and "dark flow." Instead of assuming the existence of these theoretical concepts, we take an alternative route and choose to redefine what we consider to be inertial motion as well as what constitutes an inertial frame of reference in fla...
متن کاملA Note on Dirac Spinors in a Non-flat Space-time of General Relativity
Some aspects of Dirac spinors are resumed and studied in order to interpret mathematically the P and T operations in a gravitational field. 1. Algebra and geometry of two-component spinors. From a mathematical point of view two-component spinors naturally arise when one tries to understand geometrically the well-known group homomorphism φ : SL(2,C) → SO(1, 3,R) (1.1) given by the following expl...
