OGRePy v1.2.0

v1.2.0 (2024-09-15)

• New features:
  • Tensor objects can now be compared using the T.compare() function. Two tensors are considered equal if their components are the same, and they are associated with the same metric.
  • OGRePy now correctly displays Markdown and TeX output in JupyterLite.
  • Tensor components in OGRePy are now immutable, meaning that they are specified once and for all and cannot be changed. This is done for consistency and simplicity. This means that permute() now returns a new tensor with its indices permuted instead of modifying the original tensor. Similarly, simplify() now returns a new tensor with its components simplified of simplifying the original tensor.
• Citing the package:
  • This package now has an arXiv paper! If you use this package in published research, please cite it as follows:
    • Barak Shoshany, "OGRePy: An Object-Oriented General Relativity Package for Python", doi:10.48550/arXiv.2409.03803, arXiv:2409.03803 (September 2024)
  • Added a CITATION.cff file (in YAML format) to the GitHub repository. This should add an option to get a citation in different formats directly from GitHub repository by clicking on "cite this repository" on the sidebar to the right.
  • Added a CITATION.bib file (in BibTeX format) to the GitHub repository. You can use it to easily cite this package in your papers.
  • For your convenience, the citing information can always be obtained by executing the function T.cite().
