Class field theory

Conductor (class field theory)

In algebraic number theory, the conductor of a finite abelian extension of local or global fields provides a quantitative measure of the ramification in the extension. The definition of the conductor is related to the Artin map. (Wikipedia).

Theorem 1.10 - part 11 - The Relation Between Conductors and Discriminants

In this video we apply the Serre-Tate Theorem to explain the relationship between the discriminant of the field of l-torsion (or any torsion really) and the conductor of an abelian variety.

RNT1.4. Ideals and Quotient Rings

Ring Theory: We define ideals in rings as an analogue of normal subgroups in group theory. We give a correspondence between (two-sided) ideals and kernels of homomorphisms using quotient rings. We also state the First Isomorphism Theorem for Rings and give examples.
