If f is a polynomial, or a matrix of polynomials, then f1 is the corresponding object written in the divided power monomial basis, where for example $x^2$ denotes $x^{(2)}$
i1 : S = ZZ/101[x,y] o1 = S o1 : PolynomialRing |
i2 : 2*x^2 == toDividedPowers (x^2) o2 = true |
The object toDividedPowers is a method function.
