epic Grass - symbolic calculations with anticommuting variables

Abstract epicGrass is a specialised symbolic manipulation utility for handling complicated (matrix) expressions involving commuting and anticommuting (Grassmann) variables. Its chief strength is its speed, achieved by “hardwiring” the Grassmann algebra using a table. User-friendly features include: a number of built-in functions to simplify the manipulation of matrices and expressions, an on-line help facility, sophisticated error messages and several output formats. The program has been extensively t... Title of program: EGRASS Catalogue Id: ABHY_v1_0 Nature of problem The super-mathematics, in which commuting and anticommuting variables are treated on equal footing, is used frequently in random matrix theories. The need for this program arose, when very lengthy calculations involving several thousands of terms had to be performed. Versions of this program held in the CPC repository in Mendeley Data ABHY_v1_0; EGRASS; 10.1016/0010-4655(89)90096-9 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2019)
