An Introduction to Algebraic Number Theory, and the Class Number
... We describe various algebraic invariants of number fields, as well as their applications. These applications relate to prime ramification, the finiteness of the class number, cyclotomic extensions, and the unit theorem. Finally, we present an exposition of the class number formula, which generalizes ...

... Riemann’s explicit formula connects complex zeros of meromorphic continuations of zeta functions (and L-functions) to tangible, finitistic properties of primes. Gauss’ Quadratic Reciprocity is proven via Gauss sums, which are Lagrange resolvents for cyclotomic fields. Dedekind zeta functions of quad ...
