# OGRe: An Object-Oriented General Relativity Package for Mathematica

@article{Shoshany2021OGReAO, title={OGRe: An Object-Oriented General Relativity Package for Mathematica}, author={Barak Shoshany}, journal={ArXiv}, year={2021}, volume={abs/2109.04193} }

OGRe is a modern Mathematica package for differential geometry and tensor calculus. It can be used in a variety of contexts where tensor calculations are needed, in both mathematics and physics, but it is especially suitable for general relativity — the field of physics where tensors are most commonly and ubiquitously used. Whether the user is doing cutting-edge research in general relativity or just making first steps in learning the theory, the ability to manipulate tensors and perform tensor… Expand
