The Chebotarev Density Theorem is a fundamental result in algebraic number theory that generalizes the Frobenius density theorem by asserting that the set of prime ideals in a number field, which are unramified in a given finite Galois extension and whose associated Frobenius conjugacy classes are contained in a specified subset of the Galois group, has a natural density proportional to the ratio of the cardinality of that subset to the order of the Galois group.
