Hilbert class polynomials

In commutative algebra, the Hilbert function, the Hilbert polynomial, and the Hilbert series of a graded commutative algebra finitely generated over a field are three strongly related notions which measure the growth of the dimension of the homogeneous components of the algebra. These notions have been extended to filtered algebras, and graded or filtered modules over these algebras, as well as to coherent sheaves over projective schemes. WebThese polynomials are evidently irreducible as the nonzero degree 0 polynomials are all units, and moreover every other polynomial is not an irreducible by the Fundamental Theorem of Algebra. 3.The irreducibles of R[x] are the the linear polynomials (x−a) where a ∈R, and the quadratic polynomials (x2+ax+b) with negative discriminant. These ...
