  2. Linear complementarity problem - Wikipedia

    en.wikipedia.org/wiki/Linear_complementarity_problem

    with v the Lagrange multipliers on the non-negativity constraints, λ the multipliers on the inequality constraints, and s the slack variables for the inequality constraints. The fourth condition derives from the complementarity of each group of variables ( x , s ) with its set of KKT vectors (optimal Lagrange multipliers) being ( v , λ ) .

  3. Slack variable - Wikipedia

    en.wikipedia.org/wiki/Slack_variable

    Slack variables give an embedding of a polytope into the standard f-orthant, where is the number of constraints (facets of the polytope). This map is one-to-one (slack variables are uniquely determined) but not onto (not all combinations can be realized), and is expressed in terms of the constraints (linear functionals, covectors).

  4. Bell test - Wikipedia

    en.wikipedia.org/wiki/Bell_test

    The violation of S = 2.221 ± 0.033 rejected local realism with a significance value of P = 1.02×10 −16 when taking into account 7 months of data and 55000 events or an upper bound of P = 2.57×10 −9 from a single run with 10000 events.

  5. Bell's theorem - Wikipedia

    en.wikipedia.org/wiki/Bell's_theorem

    Such a constraint would later be named a Bell inequality. Bell then showed that quantum physics predicts correlations that violate this inequality . Multiple variations on Bell's theorem were put forward in the following years, using different assumptions and obtaining different Bell (or "Bell-type") inequalities.

  6. Farkas' lemma - Wikipedia

    en.wikipedia.org/wiki/Farkas'_lemma

    There exist y 1, y 2 such that 6y 1 + 3y 2 ≥ 0, 4y 1 ≥ 0, and b 1 y 1 + b 2 y 2 < 0. Here is a proof of the lemma in this special case: If b 2 ≥ 0 and b 1 − 2b 2 ≥ 0, then option 1 is true, since the solution of the linear equations is = and =.

  7. Bounded mean oscillation - Wikipedia

    en.wikipedia.org/wiki/Bounded_mean_oscillation

    According to Nirenberg (1985, p. 703 and p. 707), [1] the space of functions of bounded mean oscillation was introduced by John (1961, pp. 410–411) in connection with his studies of mappings from a bounded set belonging to into and the corresponding problems arising from elasticity theory, precisely from the concept of elastic strain: the basic notation was introduced in a closely following ...

  8. Jarzynski equality - Wikipedia

    en.wikipedia.org/wiki/Jarzynski_equality

    In thermodynamics, the free energy difference = between two states A and B is connected to the work W done on the system through the inequality: , with equality holding only in the case of a quasistatic process, i.e. when one takes the system from A to B infinitely slowly (such that all intermediate states are in thermodynamic equilibrium).

  9. Lieb–Oxford inequality - Wikipedia

    en.wikipedia.org/wiki/Lieb–Oxford_inequality

    In the case of a single particle N = 1 the Coulomb energy vanishes, I P = 0, and the smallest possible constant can be computed explicitly as C 1 = 1.092. [2] The corresponding variational equation for the optimal ρ is the Lane–Emden equation of order 3. For two particles (N = 2) it is known that the smallest possible constant satisfies C 2 ...
