Theorem

Chebotarev Density Theorem

Number Theory

Describes the statistical distribution of Frobenius elements, and hence of prime splitting behavior, across the Galois group of a number field extension. It generalizes Dirichlet's theorem on primes in arithmetic progressions and underlies much of modern algebraic number theory.

Facts
Statement
For a finite Galois extension of a number field with Galois group G, the primes that are unramified and whose Frobenius conjugacy class lies in a fixed conjugation-stable subset of G have density equal to the proportion that subset occupies within G. 1

Equation, Concepts

Entity-backed identity for the statement-form enum value this theorem already carries, resolved to a mathematics concept by an explicit value-to-entity map (phase 3 bucket conversion, docs\design_entity_backed_browse_buckets_20260928.md). The statement-form fact itself stays on the theorem unchanged.

  • Important consequences section, first sentence
    The Chebotarev density theorem reduces the problem of classifying Galois extensions of a number field to that of describing the splitting of primes in extensions.
  • History and motivation section, closing sentence
    The general statement was proved by Nikolai Grigoryevich Chebotaryov in 1922.
