OGRe: An Object-Oriented General Relativity Toolkit

OGRe is a modern Mathematica package for tensor calculus, designed to be both powerful and user-friendly. 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. Tensors are abstract objects, which can be represented as multi-dimensional arrays once a choice of index configuration and coordinate system is made. OGRe stays true to this definition, but takes away the complexities that come with combining tensors in different representations. This is done using an object-oriented programming approach, as detailed in the documentation. The user initially defines each... Read more.
