  1. Cadabra is a symbolic computer algebra system (CAS) designed
  2. specifically for the solution of problems encountered in field theory.
  3. It has extensive functionality for tensor computer algebra, tensor
  4. polynomial simplification including multi-term symmetries, fermions
  5. and anti-commuting variables, Clifford algebras and Fierz
  6. transformations, component computations, implicit coordinate
  7. dependence, multiple index types and many more. The input format is a
  8. subset of TeX. Both a command-line and a graphical interface are
  9. available.
  10. * Designed for field-theory problems, with handling of anti-commuting
  11. and non-commuting objects without special notations for their
  12. products, gamma matrix algebra, Fierz identities, Dirac conjugation,
  13. vielbeine, flat and curved, covariant and contravariant indices,
  14. implicit dependence of tensors on coordinates, partial and covariant
  15. derivatives...
  16. * Powerful tensor simplification algorithms, not just for mono-term
  17. symmetries but also for multi-terms symmetries like the Bianchi
  18. identity, or dimensionally-dependent symmetries like the Schouten
  19. identity.
  20. * Allows for both abstract and component computations.
  21. * A standalone graphical notebook interface which can also be used as
  22. a front-end for SymPy.
  23. * Input and output using a subset of LaTeX notation.
  24. * Programmable using Python.
  25. If this SlackBuild is running on a system which has WolframEngine
  26. (available on SBo) or Mathematica (not on SBo) installed, its support
  27. in Cadabra can be enabled by setting the environment variable MMA=ON
  28. (default: MMA=OFF).
