Zel'dovich-type approximation for an inhomogeneous universe in general relativity: Second-order solutions.
The gravitational instability of inhomogeneities in the expanding universe is studied by the relativistic second-order approximation. Using the tetrad formalism we consider irrotational dust universes and get equations very similar to those given in the Lagrangian perturbation theory in Newtonian cosmology. Neglecting the cosmological constant and assuming a flat background model we give the so...
متن کاملBianchi Type V Universes with Bulk Viscosity in General Relativity
Bianchi type V bulk viscous fluid cosmological models are investigated. Using a generation technique (Camci et al., 2001), it is shown that the Einstein’s field equations are solvable for any arbitrary cosmic scale function. The viscosity coefficient of bulk viscous fluid is assumed to be a power function of mass density. Solutions for particular forms of cosmic scale functions are also obtaine...
متن کاملThe traditional approximation in general relativity
We discuss the generalisation of the so-called traditional approximation, well known in geophysics, to general relativity. We show that the approximation is applicable for rotating relativistic stars provided that one focuses on relatively thin radial shells. This means that the framework can be used to study waves in neutron star oceans. We demonstrate that, once the effects of the relativisti...
متن کاملConstructing Universes for Generic Programming
Programming languages with an expressive language for defining data types often suffer from an excess in boiler-plate code and lack of re-usable, extendible libraries. Dependently typed programming languages are especially prone to such problems. With dependent types one can specify any number of relationships between data and types, to better specify the correct behaviour of programs. Thus one...
متن کاملGravitational Lensing in Inhomogeneous Universes
I describe a new approach (developed in collaboration with D.E. Holz) to calculating the statistical distributions for magnification, shear, and rotation of images of cosmological sources due to gravitational lensing by mass inhomogeneities on galactic and smaller scales. Our approach is somewhat similar to that used in “Swiss cheese” models, but the “cheese” has been completely eliminated, the...
