Using Maple + GRTensorII in teaching basics of General Relativity and Cosmology
Ciprian A. Sporea, Dumitru N. Vulcanov
In this article we propose some Maple procedures, for teaching purposes, to study the basics of General Relativity (GR) and Cosmology. After presenting some features of GRTensorII,…
Maple+GrTensorII libraries for cosmology
Dumitru N. Vulcanov, Valentina D. Vulcanov
The article mainly presents some results in using MAPLE platform for computer algebra and GrTensorII package in doing calculations for theoretical and numerical cosmology
Doing numerical cosmology with the Cactus code
D. N. Vulcanov
The article presents some aspects concerning the construction of a new thorn for the Cactus code, a complete 3-dimensional machinery for numerical relativity. This thorn is complet…
Gravity, torsion, Dirac field and computer algebra using MAPLE and REDUCE
D. N. Vulcanov
The article presents computer algebra procedures and routines applied to the study of the Dirac field on curved spacetimes. The main part of the procedures is devoted to the constr…
Remarks on a solvable cosmological model
Ion I. Cotaescu, Dumitru N. Vulcanov
We present an exact analytical solution of the Einstein equations with cosmological constant in a spatially flat Robertson-Walker metric. This is interpreted as an isotropic Lemait…
Testing the Cactus code on exact solutions of the Einstein field equations
Dumitru N. Vulcanov, Miguel Alcubierre
The article presents a series of numerical simulations of exact solutions of the Einstein equations performed using the Cactus code, a complete 3-dimensional machinery for numerica…
