README
Cadabra is a symbolic 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,
component computations, 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.
* 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.
* Allows for both abstract and component computations.
* A standalone graphical notebook interface which can also be used as a
front-end for SymPy.
* Input and output using a subset of LaTeX notation.
* Programmable using Python.
If this SlackBuild run on a system which has Mathematica (not on SBo)
installed, the support of Mathematica can be enabled by setting the
environment variable MMA=ON (default: MMA=OFF).
