Chebotarev's Density Theorem - Important Consequences

Important Consequences

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. Specifically, it implies that as a Galois extension of K, L is uniquely determined by the set of primes of K that split completely in it. A related corollary is that if almost all prime ideals of K split completely in L, then in fact L = K.

Famous quotes containing the words important and/or consequences:

    How we shall earn our bread is a grave question; yet it is a sweet and inviting question. Let us not shirk it, as is usually done. It is the most important and practical question which is put to man. Let us not answer it hastily. Let us not be content to get our bread in some gross, careless, and hasty manner. Some men go a-hunting, some a-fishing, some a-gaming, some to war; but none have so pleasant a time as they who in earnest seek to earn their bread.
    Henry David Thoreau (1817–1862)

    The middle years are ones in which children increasingly face conflicts on their own,... One of the truths to be faced by parents during this period is that they cannot do the work of living and relating for their children. They can be sounding boards and they can probe with the children the consequences of alternative actions.
    Dorothy H. Cohen (20th century)
