SUPERCALC - A REDUCE Package for Commutator Calculations
Reference: Computer Physics Communications, 66 (1991) 363-376
Description: This paper resulted from my diploma thesis. It describes a package for REDUCE 3.3 (thus meanwhile obsolete) to work with bosonic and fermionic operators, especially to evaluate the commutators of composed operators given some fundamental commutation relations. Highlights are the possibility to work with normal or Wick ordered products and a small summation package that can handle some indefinite sums with Kronecker delta's and Heaviside functions. The whole thing is applied to determine some anomalies (and thus critical dimensions) in string theory using BRST quantisation.
