Extended Baserings
- G-algebras (or algebras of solvable type):
K<x1,...,xn |
xj xi = Cij xi xj +
Dij for all 1<i<j<n >,
where Cij are nonzero constants and
Dij are polynomials
in x1,...,xn.
- A well-ordering applied should satisfy
lm( Dij)<xixj.
- The algebra is set with the help of the
SINGULAR
data type
ring
and the matrices C and D.
- factor algebras by a two-sided ideal
- tensor products of one of the above
