Dear Simon, >> There is a difference between a polynomial (i.e., an element of a polynomial ring) and a polynomial function. Polynomials can be of arbitrary degree, over any coefficient field.
Yes I know this. But I think there is no difference between defining of PolynomialRing and PolynomialQuotientRing, assuming that you independently perform the operation by modulus. I am forcing the call of a function pol.mod(P("y^8+y")) to obtain the remainder by modulus. And I expect that monomial "y^10*a2*b1^10*p5^2" will has degree 3 (y^3*a2*b1^10*p5^2) after operation pol.mod(P("y^8+y")) in the polynomial.
