A computer algebra system for solving problems in field theory
Cadabra2 is a computer algebra system (CAS) designed specifically for
the solution of problems encountered in field theory. It has extensive
functionality for tensor computer algebra, tensor polynomial
simplification including multi-term symmetries, fermions and
anti-commuting variables, Clifford algebras and Fierz transformations,
implicit coordinate dependence, multiple index types and many more.
The input format is a subset of TeX. Both a command-line and a
graphical interface are available.
Key features of Cadabra2:
- Input and output using TeX notation.
- Designed for field-theory problems, with handling of anti-commuting
and non-commuting objects without special notations for their
products, gamma matrix algebra, Fierz identities, Dirac conjugation,
vielbeine, flat and curved, covariant and contravariant indices,
implicit dependence of tensors on coordinates, partial and covariant
derivatives...
- Powerful tensor simplification algorithms, not just for mono-term
symmetries but also for multi-terms symmetries like the Bianchi
identity, or dimensionally-dependent symmetries like the Schouten
identity.

(revision 24)
- Update to version 2.2.8:
* More versatile handling of Trace, including sorting using
cyclic symmetry (Connor).
* Fixes for combine (Connor).
* Save command-line history (Connor).
* Make imported notebooks use the default post_process function.
* Make unwrap move scalars out of exterior (wedge) products, see
this Q&A post.
* Fix bug with indices with accents (github/166).
* Added a cadabra2latex command to convert notebooks to LaTeX.
* Fixed issue building with latest Homebrew on macOS.
* Fixed Windows build issues and add python path settings at
runtime.
* Fixed bug with multipliers not reducing to canonical form.
- Add Fix-linking-of-cadabra-module.patch
- Remove timestamps from Doxygen generated HTML files, drop
obsolete cadabra2-rpmlintrc
- Use system jsoncpp
- Drop conditionals for obsolete distro versions
- Remove lots of unused/obsolete TeX BuildRequires.
- Update to version 2.2.7:
* Added cdb.utils.develop and cdb.relativity.abstract.
* Added authentication token to all client-server communication.
* Various extensions to the Trace property.
* Make property info available from Python (Dominic).
* Fixed integration by parts with index-less derivatives.
* Added eliminate_vielbein.
* Fixed display of lists of sympy expressions.
* Fixed (finally) UTF8 input for non-English symbols.
