  2. Free will theorem - Wikipedia

    en.wikipedia.org/wiki/Free_will_theorem

    In their later 2009 paper, "The Strong Free Will Theorem", [2] Conway and Kochen replace the Fin axiom by a weaker one called Min, thereby strengthening the theorem. The Min axiom asserts only that two experimenters separated in a space-like way can make choices of measurements independently of each other.

  3. Exponential time hypothesis - Wikipedia

    en.wikipedia.org/wiki/Exponential_time_hypothesis

    The strong exponential time hypothesis implies that it is not possible to find -vertex dominating sets more quickly than in time (). [ 8 ] The exponential time hypothesis implies also that the weighted feedback arc set problem on tournaments does not have a parametrized algorithm with running time O ( 2 o ( OPT ) n O ( 1 ) ) {\textstyle O(2^{o ...

  4. Goldbach's weak conjecture - Wikipedia

    en.wikipedia.org/wiki/Goldbach's_weak_conjecture

    This conjecture is called "weak" because if Goldbach's strong conjecture (concerning sums of two primes) is proven, then this would also be true. For if every even number greater than 4 is the sum of two odd primes, adding 3 to each even number greater than 4 will produce the odd numbers greater than 7 (and 7 itself is equal to 2+2+3).

    They are called the strong law of large numbers and the weak law of large numbers. [16] [1] Stated for the case where X 1, X 2, ... is an infinite sequence of independent and identically distributed (i.i.d.) Lebesgue integrable random variables with expected value E(X 1) = E(X 2) = ... = μ, both versions of the law state that the sample average

  7. Simply typed lambda calculus - Wikipedia

    en.wikipedia.org/wiki/Simply_typed_lambda_calculus

    In the 1930s Alonzo Church sought to use the logistic method: [a] his lambda calculus, as a formal language based on symbolic expressions, consisted of a denumerably infinite series of axioms and variables, [b] but also a finite set of primitive symbols, [c] denoting abstraction and scope, as well as four constants: negation, disjunction, universal quantification, and selection respectively ...

    The following scores (in addition to 1, 2, and 4) cannot be made from multiples of 5 and 7 and so are almost never seen in sevens: 3, 6, 8, 9, 11, 13, 16, 18 and 23. By way of example, none of these scores was recorded in any game in the 2014-15 Sevens World Series .

    In 1999, a theorem due to Haga provided constructions used to divide the side of a square into rational fractions. [19] [20] In late 2001 and early 2002, Britney Gallivan proved the minimum length of paper necessary to fold it in half a certain number of times and folded a 4,000-foot-long (1,200 m) piece of toilet paper twelve times.
