Approximate Symmetries of Lagrangians for Plane Symmetric Gravitational Wave-like Spacetimes
Using Lie symmetry methods for differential equations we have investigated the symmetries of a Lagrangian for a plane symmetric static spacetime. Perturbing this Lagrangian we explore its approximate symmetries. It has a non-trivial first-order approximate symmetry.
متن کاملNoether Symmetries of the Area-Minimizing Lagrangian
It is shown that the Lie algebra of Noether symmetries for the Lagrangian minimizing an n − 1 area enclosing a constant n-volume in a Euclidean space is so n ⊕sR and in a space of constant curvature the Lie algebra is so n . Furthermore, if the space has one section of constant curvature of dimension n1, another of n2, and so on to nk and one of zero curvature of dimension m, with n ≥ ∑kj 1 nj ...
متن کاملShockWaves in Plane Symmetric Spacetimes
We consider Einstein’s equations coupled to the Euler equations in plane symmetry, with compact spatial slices and constant mean curvature time. We show that for a wide variety of equations of state and a large class of initial data, classical solutions break down in finite time. The key mathematical result is a new theorem on the breakdown of solutions of systems of balance laws. We also show ...
متن کاملApproximate Symmetries and the Energy in Spacetimes
There is a problem of defining energy in time-varying spacetimes as energy is not conserved in them. The problem is particularly severe for gravitational waves as there is no conventional stress-energy tensor. The gravitational field is given by the Weyl tensor. The gravitational field is given by the Weyl tensor but that does not provide a measure of the energy. Pseudo tensors are introduced b...
متن کاملLie symmetries of the energy-momentum tensor for plane symmetric static spacetimes
Matter collineations (MCs) are the vector fields along which the energymomentum tensor remains invariant under the Lie transport. Invariance of the metric, the Ricci and the Riemann tensors have been studied extensively and the vectors along which these tensors remain invariant are called Killing vectors (KVs), Ricci collineations (RCs) and curvature collineations (CCs), respectively. In this p...
