Cadabra Description

Computer algebra system designed specifically for the solution of problems encountered in field theory Cadabra is a computer algebra system designed specifically for the solution of problems encountered in field theory. Cadabra has extensive functionality for 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 graphical interface and a command-line are available. Here are some key features of "Cadabra": · 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. Requirements: · Apple XCode What's New in This Release: · Better handling of nested partial derivatives. · Various pattern matching bug fixes. · Added window icons.
