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. |
