- `Polynomial.map_contract`: `Polynomial.map` and `Polynomial.contract` commutes - `Irreducible.natDegree_pos`: an irreducible polynomial over a field must have positive degree (not true if it's not a field) - `Polynomial.Monic.nextCoeff_pow`: corollary of `Polynomial.Monic.nextCoeff_mul` - `Polynomial.exists_monic_irreducible_factor`: a polynomial over a field which is not a unit must have a monic irreducible factor (not true if it's not a field)
