(mathematics) A result about the decomposability of measure spaces, playing an important role in the theory of Banach spaces. In brief, it states that every complete measure space is decomposable into "non-atomic parts" (copies of products of the unit interval [0,1] on the reals), and "purely atomic parts", using the counting measure on some discrete space.

A theorem stating that, if we have free will in the sense that our choices are not a function of the past, then, subject to certain assumptions, so must some elementary particles.

Abbreviation of Kochen-Specker theorem.

(economics) The idea that capital accumulation is equal to production minus consumption.

(mathematics) A formula for the exponent of the highest power of a prime number that divides a given binomial coefficient.

(physics) A no-go theorem stating that no physical theory of local hidden variables can ever reproduce all of the predictions of quantum mechanics.

A parody of the three laws of thermodynamics in terms of a person playing a game: (1) you can't win; (2) you can't break even; (3) you can't even get out of the game.

plural of spectral theorem

(group theory) A theorem which proves that, given a mind swap machine that can't be used on the same pair of people more than once, it is possible to reverse any number of mind swaps by introducing two more people that did not have their minds swapped with anyone before.

(group theory) The theorem stating that every group G is isomorphic to a subgroup of the symmetric group acting on G.
