The article mainly presents some results in using MAPLE platform for computer algebra (CA) and GrTensorII package in doing calculations for theoretical and numerical cosmology. AMS Subject Classification: 68W30, 83C05, 85A40
The article illustrates the graphical study of geodesic motion on curved space-times (mainly exact solutions of Einstein equations) using the symbolic, numerical and graphical computation facilities of Maple platform. The example of null geodesics on Schwarzschild solution is completely processed. The geodesic curves are plotted directly using DEtools… (More)
