Higher–Order Corrections to the Effective Gravitational Action from Noether Symmetry Approach
Higher–order corrections of Einstein–Hilbert action of general relativity can be recovered by imposing the existence of a Noether symmetry to a class of theories of gravity where Ricci scalar R and its d’Alembertian 2R are present. In several cases, it is possible to get exact cosmological solutions or, at least, to simplify dynamics by recovering constants of motion. The main result is that a ...
متن کاملHigher Order Corrections in Gravitational Microlensing
We show that, in cosmological microlensing, corrections of order v/c ∼ ∆λ/λ, to the deflection angle of light beams from a distant source are not negligible and that all microlensing quantities should be corrected up to this order independently of the cosmological model used. keywords: microlensing, redshift, cosmology. In the last decade, gravitational lensing has become one of the most powerf...
متن کاملHigher order corrections to lensing parameters for extended gravitational lenses
We discuss the contribution to the characteristic lensing quantities, i.e. the deflection angle and Einstein radius, due to the higher order terms (e.g. the gravitomagnetic terms) considered in the lens potential. The cases we analyze are the singular isothermal sphere and the disk of spiral galaxies. It is possible to see that the perturbative effects could be of the order 10−3 with respect to...
متن کاملOn the Higher Order Corrections to Heavy Quark Effective Theory
We show that the different ways of deriving the Heavy Quark Effective Theory (HQET) lead to equivalent theories. The equivalence can be established through a careful redefinition of the field variables. We demonstrate the equivalence to order 1 m in the presence of a constant electric field.
متن کاملfrom linguistics to literature: a linguistic approach to the study of linguistic deviations in the turkish divan of shahriar
chapter i provides an overview of structural linguistics and touches upon the saussurean dichotomies with the final goal of exploring their relevance to the stylistic studies of literature. to provide evidence for the singificance of the study, chapter ii deals with the controversial issue of linguistics and literature, and presents opposing views which, at the same time, have been central to t...
