  3. Equation solving - Wikipedia

    en.wikipedia.org/wiki/Equation_solving

    In other words, a solution is a value or a collection of values (one for each unknown) such that, when substituted for the unknowns, the equation becomes an equality. A solution of an equation is often called a root of the equation, particularly but not only for polynomial equations. The set of all solutions of an equation is its solution set.

  4. Two-state solution - Wikipedia

    en.wikipedia.org/wiki/Two-state_solution

    The two-state solution is supported by many countries, and the Palestinian Authority. [1] Israel currently does not support the idea, though it has in the past. [2] The first proposal for separate Jewish and Arab states in the territory was made by the British Peel Commission report in 1937. [3]

  5. Extraneous and missing solutions - Wikipedia

    en.wikipedia.org/wiki/Extraneous_and_missing...

    Extraneous solutions are not too difficult to deal with because they just require checking all solutions for validity. However, more insidious are missing solutions, which can occur when performing operations on expressions that are invalid for certain values of those expressions.

  6. Exact solutions in general relativity - Wikipedia

    en.wikipedia.org/wiki/Exact_solutions_in_general...

    Noteworthy examples of vacuum solutions, electrovacuum solutions, and so forth, are listed in specialized articles (see below). These solutions contain at most one contribution to the energy–momentum tensor, due to a specific kind of matter or field. However, there are some notable exact solutions which contain two or three contributions ...

    Third stage: host opens a door. Fourth stage: player makes a final choice. The player wants to win the car, the TV station wants to keep it. This is a zero-sum two-person game. By von Neumann's theorem from game theory, if we allow both parties fully randomized strategies there exists a minimax solution or Nash equilibrium. [9]

    en.wikipedia.org/wiki/The_Screwfly_Solution

    "The Screwfly Solution" is a 1977 science fiction short story by Raccoona Sheldon, a pen name for American psychologist Alice Sheldon, who was better known by her other nom de plume James Tiptree Jr.

  9. Wave equation - Wikipedia

    en.wikipedia.org/wiki/Wave_equation

    Eigenmodes are useful in constructing a full solution to the wave equation, because each of them evolves in time trivially with the phase factor , so that a full solution can be decomposed into an eigenmode expansion: (,) = (,), or in terms of the plane waves, (,) = + (+) + () = + (+) + () = + (+), which is exactly in the same form as in the ...
