Noether Symmetry in f(T) Theory at the anisotropic universe
As it is well known, symmetry plays a crucial role in the theoretical physics. On other hand, the Noether symmetry is a useful procedure to select models motivated at a fundamental level, and to discover the exact solution to the given lagrangian. In this work, Noether symmetry in f(T) theory on a spatially homogeneous and anisotropic Bianchi type I universe is considered. We discuss the Lagran...
متن کاملT F S C M T G T F
In this paper, we extend our ideas on model transformations as functors discussed in the previous issue and embed this concept into the framework of graph transformation systems. We show that under certain restrictions of the rules model transformations by graph transformation are functors.
متن کاملf(T) teleparallel gravity and cosmology.
Over recent decades, the role of torsion in gravity has been extensively investigated along the main direction of bringing gravity closer to its gauge formulation and incorporating spin in a geometric description. Here we review various torsional constructions, from teleparallel, to Einstein-Cartan, and metric-affine gauge theories, resulting in extending torsional gravity in the paradigm of f ...
متن کاملIntrinsic colour calibration for F, G, K stars
We derive an intrinsic colour calibration for F–K stars using broad band Johnson colours and line indices KP and HP2. Through this calibration we can determine E(B−V ) of an individual star within 0.03 mag. The E(B−V ) values thus derived are in excellent agreement with those derived from Strömgren photometry through the Schuster & Nissen (1989) calibration. The agreement is also good with the ...
متن کاملAnisotropic Stars in General Relativity
We present a class of exact solutions of Einstein’s gravitational field equations describing spherically symmetric and static anisotropic stellar type configurations. The solutions are obtained by assuming a particular form of the anisotropy factor. The energy density and both radial and tangential pressures are finite and positive inside the anisotropic star. Numerical results show that the ba...
