Noether Symmetries and Conservation Laws in Static Cylindrically Symmetric Spacetimes via Rif Tree Approach
نویسندگان
چکیده
A new approach is adopted to completely classify the Lagrangian associated with static cylindrically symmetric spacetime metric via Noether symmetries. The determining equations representing symmetries are analyzed using a Maple algorithm that imposes different conditions on coefficients under which spacetimes admit of dimensions. These used solve equations, giving explicit form vector fields obtained symmetry generators in Noether’s theorem find expressions for corresponding conservation laws. singularity metrics discussed by finding their Kretschmann scalar.

Symmetries of the Energy-Momentum Tensor of Cylindrically Symmetric Static Spacetimes
We investigate matter symmetries of cylindrically symmetric static spacetimes. These are classified for both cases when the energymomentum tensor is non-degenerate and also when it is degenerate. It is found that the non-degenerate energy-momentum tensor gives either three, four, five, six, seven or ten independent matter collineations in which three are isometries and the rest are proper. The ...
متن کاملGyroscope Precession in Cylindrically Symmetric Spacetimes
We present calculations of gyroscope precession in spacetimes described by Levi-Civita and Lewis metrics, under different circumstances. By doing so we are able to establish a link between the parameters of the metrics and observable quantities, providing thereby a physical interpretation for those parameters, without specifying the source of the field. ∗Also at Deapartamento de Fisica, Faculta...
متن کاملSpherically Symmetric Static Spacetimes
In this paper we discuss matter inheritance collineations by giving a complete classification of spherically symmetric static spacetimes by their matter inheritance symmetries. It is shown that when the energy-momentum tensor is degenerate, most of the cases yield infinite dimensional matter inheriting symmetries. It is worth mentioning here that two cases provide finite dimensional matter inhe...
متن کاملNoether Symmetries and Covariant Conservation Laws in Classical, Relativistic and Quantum Physics
We review the Lagrangian formulation of (generalised) Noether symmetries in the framework of Calculus of Variations in Jet Bundles, with a special attention to so-called “Natural Theories” and “Gauge-Natural Theories” that include all relevant Field Theories and physical applications (from Mechanics to General Relativity, to Gauge Theories, Supersymmetric Theories, Spinors, etc.). It is discuss...
متن کاملSymmetries of Conservation Laws
We apply techniques of symmetry group analysis in solving two systems of conservation laws: a model of two strictly hyperbolic conservation laws and a zero pressure gas dynamics model, which both have no global solution, but whose solution consists of singular shock waves. We show that these shock waves are solutions in the sense of 1-strong association. Also, we compute all projectable symmetr...
