Systems related to (Non)Commutative Algebra & Algebraic Geometry


Bergman (version 0.9) is an experimental program developed by Prof. Joergen Backelin in Portable Standard Lisp to calculate a Groebner basis from homogeneous input (although there are some possibilities to homogenise/dehomogenise an arbitrary commutative input), by polynomials in the commutative or the non-commutative polynomial ring over the rationals or a finite prime field, in a finite number of variables.
