On the two-body problem in general relativity

چکیده
We consider the two-body problem in post-Newtonian approximations of general relativity. We report the recent results concerning the equations of motion, and the associated Lagrangian formulation, of compact binary systems, at the third post-Newtonian order (∼ 1/c beyond the Newtonian acceleration). These equations are necessary when constructing the theoretical templates for searching and analyzing the gravitational-wave signals from inspiralling compact binaries in VIRGO-type experiments. c © 2001 Académie des sciences/Éditions scientifiques et médicales Elsevier SAS general relativity/equations of motion Sur le problème des deux corps en relativité générale Résumé. Nous considérons le problème des deux corps dans l’approximation post-newtonienne de la relativité générale. Nous présentons les résultats récents concernant les équations du mouvement, et la formulation lagrangienne associée, de systèmes binaires d’objets compacts, au troisième ordre post-newtonien (∼ 1/c après l’accélération newtonienne). Ces équations sont utilisées dans la construction des filtres théoriques pour la détection et l’analyse des signaux d’ondes gravitationnelles provenant des binaires compactes spiralantes dans les expériences du type VIRGO. c © 2001 Académie des sciences/Éditions scientifiques et médicales Elsevier SAS relativité générale/équations du mouvement Note présentée par First name NAME S1296-2147(01)01171-?/FLA c © 2001 Académie des sciences/Éditions scientifiques et médicales Elsevier SAS.

THE PC-TAU METHOD ON THE SOLUTION OF A MODEL OF AN ISOLATED COSMIC STRING
In this paper, we adapt the operational Tau Method for personal computers and apply it to a system of two nonlinear second order ordinary differential equations which are related to general relativity. The interesting behaviour this problem exhibits in its numerical treatment is discussed. In this problem, we try to use the Tau perturbation term to locate the correct solution of this nonlin...
متن کاملBulk Viscous Bianchi Type VI0 Cosmological Model in the Self-creation Theory of Gravitation and in the General Theory of Relativity
In the second self-creation theory of gravitation and in the general theory of relativity, Bianchi type VI0 cosmological model in the presence of viscous fluid is studied. An exact solution of the field equations is given by considering the cosmological model yields a constant decelerations parameter q=constant and the coefficients of the metric are taken as A(t)=[c1t+c<su...
متن کاملکوانتش گرانش و بررسی هندسی مکانیک کوانتمی
We elaborate on some recent results on a solution of the Hilbert-space problem in minisuperspace quantum cosmology and discuss the consequences of making the (geometry of the) Hilbert space of ordinary nonrelativistic quantum systems time-dependent. The latter reveals a remarkable similarity between Quantum Mechanics and General Relativity.
متن کاملEinstein structures on four-dimensional nutral Lie groups
When Einstein was thinking about the theory of general relativity based on the elimination of especial relativity constraints (especially the geometric relationship of space and time), he understood the first limitation of especial relativity is ignoring changes over time. Because in especial relativity, only the curvature of the space was considered. Therefore, tensor calculations should be to...
متن کاملThe Principle of Relativity: From Ungar’s Gyrolanguage for Physics to Weaving Computation in Mathematics
This paper extends the scope of algebraic computation based on a non standard $times$ to the more basic case of a non standard $+$, where standard means associative and commutative. Two physically meaningful examples of a non standard $+$ are provided by the observation of motion in Special Relativity, from either outside (3D) or inside (2D or more), We revisit the ``gyro''-theory ...
