Anderson's Theorem - Statement of The Theorem

Statement of The Theorem

Let K be a convex body in n-dimensional Euclidean space Rn that is symmetric with respect to reflection in the origin, i.e. K = −K. Let f : RnR be a non-negative, symmetric, globally integrable function; i.e.

  • f(x) ≥ 0 for all xRn;
  • f(x) = f(−x) for all xRn;

Suppose also that the super-level sets L(f, t) of f, defined by

are convex subsets of Rn for every t ≥ 0. (This property is sometimes referred to as being unimodal.) Then, for any 0 ≤ c ≤ 1 and yRn,

Famous quotes containing the words statement of, statement and/or theorem:

    Most personal correspondence of today consists of letters the first half of which are given over to an indexed statement of why the writer hasn’t written before, followed by one paragraph of small talk, with the remainder devoted to reasons why it is imperative that the letter be brought to a close.
    Robert Benchley (1889–1945)

    Truth is that concordance of an abstract statement with the ideal limit towards which endless investigation would tend to bring scientific belief, which concordance the abstract statement may possess by virtue of the confession of its inaccuracy and one-sidedness, and this confession is an essential ingredient of truth.
    Charles Sanders Peirce (1839–1914)

    To insure the adoration of a theorem for any length of time, faith is not enough, a police force is needed as well.
    Albert Camus (1913–1960)
