# SparseUnivariatePolynomialFunctions2(R, S)ΒΆ

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.
