Eulerian Coordinates for Relativistic Fluids: Hamiltonian Rest-Frame Instant Form, Relative Variables, Rotational Kinematics

چکیده
We study the rest-frame instant form of a new formulation of relativistic perfect fluids in terms of Eulerian coordinates. After the separation of the relativistic center of mass from the relative variables on the Wigner hyperplanes, we define orientational and shape variables for the fluid, viewed as a relativistic extended deformable body, by introducing dynamical body frames. Finally we define Dixon’s multipoles for the fluid.

Generalized Eulerian Coordinates for Relativistic Fluids: Hamiltonian Rest-Frame Instant Form, Relative Variables, Rotational Kinematics
We study the rest-frame instant form of a new formulation of relativistic perfect fluids in terms of new generalized Eulerian configuration coordinates. After the separation of the relativistic center of mass from the relative variables on the Wigner hyper-planes, we define orientational and shape variables for the fluid, viewed as a relativistic extended deformable body, by introducing dynamic...
متن کاملThe Rest - Frame Instant Form of Relativistic Perfect Fluids with Equation of State ρ = ρ ( n , s ) and of Non - Dissipative Elastic Materials
For perfect fluids with equation of state ρ = ρ(n, s), Brown [1] gave an action principle depending only on their Lagrange coordinates αi(x) without Clebsch potentials. After a reformulation on arbitrary spacelike hypersurfaces in Minkowski spacetime, the Wigner-covariant rest-frame instant form of these perfect fluids is given. Their Hamiltonian invariant mass can be given in closed form for t...
متن کاملThe models of delocalized membranes
The generally adopted approach in theory of relativistic strings and membranes, is similar to use of Lagrange coordinates in continious media mechanics. One can use an alternative approach, which is similar to use of Euler coordinates. Under such approach the consideration of thick (delocalized) membranes is natural. Membrane kinematics, which coorespond to Euler coordinates is constructed. Var...
متن کاملJa n 20 01 The Rest - Frame Instant Form of Metric Gravity
In a special class of globally hyperbolic, topologically trivial, asymptotically flat at spatial infinity spacetimes selected by the requirement of absence of supertranslations (compatible with Christodoulou-Klainermann spacetimes) it is possible to define the rest-frame instant form of ADM canonical gravity by using Dirac’s strategy of adding ten extra variables at spatial infinity and ten ext...
متن کاملHamiltonian Relativistic Two-Body Problem: Center of Mass and Orbit Reconstruction
After a short review of the history and problems of relativistic Hamiltonian mechanics with action-at-a-distance inter-particle potentials, we study isolated two-body systems in the rest-frame instant form of dynamics. We give explicit expressions of the relevant relativistic notions of center of mass, we determine the generators of the Poincare’ group in presence of interactions and we show ho...
