Birch-Tate Conjecture

Number Theory

The Birch-Tate conjecture, in algebraic K-theory, is a conjecture proposed by Bryan John Birch and John Tate relating the K2 group of a number field to its Dedekind zeta function.

Facts
Statement
For a totally real number field F, let N be the largest positive integer such that adjoining the Nth roots of unity to F produces an extension whose Galois group is an elementary abelian 2 group. The Birch-Tate conjecture states that the order of the K2 group of the ring of integers of F equals the absolute value of N times the Dedekind zeta function of F evaluated at negative 1. 1
Progress Toward Resolution
The conjecture remains open in general, though progress has followed from work on Iwasawa theory, in particular from proofs of the main conjecture of Iwasawa theory. 1
