- Cadabra is a computer algebra system designed specifically for the solution of problems encountered in classical field theory, quantum field theory and string theory. The first version of Cadabra was developed around 2001 for computing higher-derivative string theory correction to supergravity. Released under the GNU General Public License, Cadabra is free software. 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 command-line and a graphical interface are available. A Java program inspired by Cadabra called Redberry was developed between 2013 and 2016. It achieved faster speeds for most index contractions with an approach based on the graph isomorphism problem rather than canonicalisation. (en)

Liberado bajo la Licencia Pública General de GNU, Cadabra es software libre. Posee gran cantidad de funcionalidades para la simplificación polinómica de tensor incluyendo simetrías, fermiones y variables anti-desplazamiento, transformadas de Fierz y álgebra de Clifford, dependencias implícitas coordenadas, múltiples índices y otras funciones más. El formato de entrada es un subconjunto de TeX. Cadabra puede funcionar bajo una interfaz de línea de comando como también bajo una interfaz gráfica. (es)
