GroebnerDegRevLex Command
CAS Syntax
- GroebnerDegRevLex( <List of Polynomials> )
-
Computes the Gröbner basis of the list of the polynomials with respect to graded reverse lexicographical ordering of the variables (also known as total degree reverse lexicographic ordering, degrevlex or grevlex ordering).
GroebnerDegRevLex({x^3 - y - 2, x^2 + y + 1}) yields {\( y^{2} - x + 3 y + 3, x y + x + y + 2, x^{2} + y +
1 \)}.
- GroebnerDegRevLex( <List of Polynomials>, <List of Variables> )
-
Computes the Gröbner basis of the list of the polynomials with respect to graded reverse lexicographical ordering of the given variables (also known as total degree reverse lexicographic ordering, degrevlex or grevlex ordering).
GroebnerDegRevLex({x^3 - y - 2, x^2 + y + 1}, {y, x}) yields {\( x^{2} + y + 1, y x + y + x + 2, y^{2} + 3y - x + 3\)}.
