  2. Kolmogorov–Arnold representation theorem - Wikipedia

    en.wikipedia.org/wiki/Kolmogorov–Arnold...

    Therefore, the solution of an algebraic equation of degree can be represented as a superposition of functions of two variables if < and as a superposition of functions of variables if . For n = 7 {\displaystyle n=7} the solution is a superposition of arithmetic operations, radicals, and the solution of the equation y 7 + b 3 y 3 + b 2 y 2 + b 1 ...

  3. Superposition principle - Wikipedia

    en.wikipedia.org/wiki/Superposition_principle

    The superposition principle, [1] also known as superposition property, states that, for all linear systems, the net response caused by two or more stimuli is the sum of the responses that would have been caused by each stimulus individually.

  4. Quantum superposition - Wikipedia

    en.wikipedia.org/wiki/Quantum_superposition

    Quantum superposition is a fundamental principle of quantum mechanics that states that linear combinations of solutions to the Schrödinger equation are also solutions of the Schrödinger equation. This follows from the fact that the Schrödinger equation is a linear differential equation in time and position.

  5. Superposition calculus - Wikipedia

    en.wikipedia.org/wiki/Superposition_calculus

    Superposition is refutation complete—given unlimited resources and a fair derivation strategy, from any unsatisfiable clause set a contradiction will eventually be derived. Many (state-of-the-art) theorem provers for first-order logic are based on superposition (e.g. the E equational theorem prover), although only a few implement the pure ...

  6. Linear time-invariant system - Wikipedia

    en.wikipedia.org/wiki/Linear_time-invariant_system

    Block diagram illustrating the superposition principle and time invariance for a deterministic continuous-time single-input single-output system. The system satisfies the superposition principle and is time-invariant if and only if y 3 (t) = a 1 y 1 (t – t 0) + a 2 y 2 (t – t 0) for all time t, for all real constants a 1, a 2, t 0 and for all inputs x 1 (t), x 2 (t).

  8. Green's function - Wikipedia

    en.wikipedia.org/wiki/Green's_function

    Through the superposition principle, given a linear ordinary differential equation (ODE), =, one can first solve =, for each s, and realizing that, since the source is a sum of delta functions, the solution is a sum of Green's functions as well, by linearity of L.

  9. Linear combination - Wikipedia

    en.wikipedia.org/wiki/Linear_combination

    is the linear combination of vectors and such that = +. In mathematics, a linear combination or superposition is an expression constructed from a set of terms by multiplying each term by a constant and adding the results (e.g. a linear combination of x and y would be any expression of the form ax + by, where a and b are constants).
