Hilbert class polynomials
WebThe Hilbert polynomial of a sheaf F gives partial information about the degrees of the Chern classes c i ( F). H n − i, where H is the hyperplane class of O ( 1) and n = dim X. There is little hope in recovering the classes c i ( F) just from these intersection numbers. To elaborate, the Hirzebruch-Riemann-Roch states that.

WebDefine the Hilbert class polynomial HD(x) ∈ Z[x] as the unique monic polynomial whose roots are precisely the j-invariants of the elliptic curves with complex multipli-cation by OD. These roots are referred to as singular moduli of discriminant D. The degree of the Hilbert class polynomial is h(D). Define further Sp(x) ∈ Fp[x] to be the Webthe elliptic curve C=Ois an algebraic integer, and its minimal polynomial H D(X) is the Hilbert class polynomial for the discriminant D. This polynomial splits com-pletely in F q, and its roots are the j-invariants of elliptic curves with endomorphism ring isomorphic to O. To construct such a curve, we reduce H Dmod p, compute a root in F
