# GRLite and GRTensorJ: Graphical user interfaces to the computer algebra system GRTensorII

@inproceedings{Ishak1999GRLiteAG, title={GRLite and GRTensorJ: Graphical user interfaces to the computer algebra system GRTensorII}, author={Mustapha Ishak and Peter Musgrave and John Mourra and Jonathan Stern and Kayll Lake}, year={1999} }

Two open graphical user interfaces to the computer algebra system GRTensorII are described. Each can be run locally or via the Internet. These provide students and researchers in the area of General Relativity and related fields with advanced truly portable tools that reduce many complex calculations to elementary functions.

This work study and compare the features of gravitational entropy near the throat of transversable wormholes formed by exotic matter and wormholes in galactic halos and finds that both are endowed with an entropic behaviour similar to Hawking–Bekenstein's entropy of nonrotating and null charge black holes.
