SolvableSkewPolynomialCategory(R, Expon)

skpol.spad line 6 [edit on github]

• R: Ring

• Expon: OrderedAbelianMonoidSup

This is the category of polynomials in noncommutative variables over noncommutative rings. We do not assume that variables and elements of the base ring commute. We assume that the polynomial ring is of solvable type, so noncommutative version of Buchberger algorithm works.
