Discriminant of An Algebraic Number Field - Relation To Other Quantities

Relation To Other Quantities

  • When embedded into, the volume of the fundamental domain of OK is (sometimes a different measure is used and the volume obtained is, where r2 is the number of complex places of K).
  • Due to its appearance in this volume, the discriminant also appears in the functional equation of the Dedekind zeta function of K, and hence in the analytic class number formula, and the Brauer–Siegel theorem.
  • The relative discriminant of K/L is the Artin conductor of the regular representation of the Galois group of K/L. This provides a relation to the Artin conductors of the characters of the Galois group of K/L, called the conductor-discriminant formula.

Famous quotes containing the words relation to, relation and/or quantities:

    The proper study of mankind is man in his relation to his deity.
    —D.H. (David Herbert)

    Concord is just as idiotic as ever in relation to the spirits and their knockings. Most people here believe in a spiritual world ... in spirits which the very bullfrogs in our meadows would blackball. Their evil genius is seeing how low it can degrade them. The hooting of owls, the croaking of frogs, is celestial wisdom in comparison.
    Henry David Thoreau (1817–1862)

    James Brown and Frank Sinatra are two different quantities in the universe. They represent two different experiences of the world.
    Imamu Amiri Baraka [Everett Leroi Jones] (b. 1934)
