Normal Fermi-Walker Derivative in E_{1}^{3}
نویسندگان
چکیده مقاله:
In this paper, firstly, in $E_1^3$, we defined normal Fermi-Walker derivative and applied for the adapted frame. Normal Fermi-Walker parallelism, normal non-rotating frame, and Darboux vector expressions of normal Fermi-Walker derivative by normal Fermi-Walker derivative are given for adapted frame. Being conditions of normal Fermi-Walker derivative and normal non-rotating frame are examined for frames throughout spacelike, timelike, lightlike curves. It is shown that the vector field which takes part in cite {Beyhan(2016)} is normal Fermi-Walker parallel by the normal Fermi-Walker derivative throughout the spacelike, timelike, and lightlike general helix. Also, we show that the Frenet frame is a normal non-rotating frame using the normal Fermi-Walker derivative. Afterward, we testified that the adapted frame is a normal non-rotating frame throughout the spacelike, timelike, and lightlike general helix.

General Transformation Formulas for Fermi-Walker Coordinates
We calculate the transformation and inverse transformation, in the form of Taylor expansions, from arbitrary coordinates to Fermi-Walker coordinates in tubular neighborhoods of arbitrary timelike paths for general spacetimes. Explicit formulas for coefficients and the Jacobian matrix are given.
متن کاملFermi Normal Coordinates and Fermion Curvature Couplings in General Relativity
We study gravitational curvature effects in circular and radial geodesics in static, spherically symmetric space-times, using Fermi normal coordinates. We first set up these coordinates in the general case, and then use this to study effective magnetic fields due to gravitational curvature in the exterior and interior Schwarzschild, Janis-Newman-Winicour, and Bertrand space-times. We show that ...

Partiendo de la teoŕıa desarrollada en la tesis “Paralelismo y geodésicas en variedades conformes” [5], se utiliza la conexión de Fermi–Walker y el tensor conforme de Schouten para describir los invariantes conformes clásicos asociados a curvas en el espacio conforme plano R. En particular, estos resultados se aplican al estudio de dos ejemplos especiales de curvas: los ćırculos y las hélices. ...
متن کاملSpectral Function and Kinetic Equation for Normal Fermi Liquid
On the basis of the Kadanoff-Baym (KB) version of the time-dependent Green’s function method a new ansatz for the approximation of a spectral function is offered. The ansatz possesses all the advantages of quasiparticle (QP) and extended quasiparticle (EQP) approximations and satisfies the KB-equation for a spectral function in the case of slightly non-equilibrium system when disturbances in sp...
