Lagrangian theory of structure formation in relativistic cosmology. IV. Lagrangian approach to gravitational waves
Fosca Al Roumi, Thomas Buchert, Alexander Wiegand
The relativistic generalization of the Newtonian Lagrangian perturbation theory is investigated. In previous works, the perturbation and solution schemes that are generated by the…
Lagrangian theory of structure formation in relativistic cosmology III: gravitoelectric perturbation and solution schemes at any order
Alexandre Alles, Thomas Buchert, Fosca Al Roumi +1
The relativistic generalization of the Newtonian Lagrangian perturbation theory is investigated. In previous works, the first-order trace solutions that are generated by the spatia…
Relativistic Lagrangian displacement field and tensor perturbations
Cornelius Rampf, Alexander Wiegand
We investigate the purely spatial Lagrangian coordinate transformation from the Lagrangian to the basic Eulerian frame. We demonstrate three techniques for extracting the relativis…
Lagrangian theory of structure formation in relativistic cosmology II: average properties of a generic evolution model
Thomas Buchert, Charly Nayet, Alexander Wiegand
Kinematical and dynamical properties of a generic inhomogeneous cosmological model, spatially averaged with respect to free-falling (generalized fundamental) observers, are investi…
