SparseUnivariatePolynomialFunctions2(R, S)

• R: Ring

• S: Ring

This package lifts a mapping from coefficient rings R to S to a mapping from sparse univariate polynomial over R to a sparse univariate polynomial over S. Note that the mapping is assumed to send zero to zero, since it will only be applied to the non-zero coefficients of the polynomial.

map: (R -> S, SparseUnivariatePolynomial R) -> SparseUnivariatePolynomial S

map(func, poly) creates a new polynomial by applying func to every non-zero coefficient of the polynomial poly.
