function symbol
51Prime (symbol) — This article is about the symbol. For the type of number, see Prime number. For other uses, see Prime (disambiguation). ′ Prime Punc …
52Vertex function — In quantum electrodynamics, the vertex function describes the coupling between a photon and an electron beyond the leading order of perturbation theory. In particular, it is the one particle irreducible correlation function involving the fermion… …
53Ramanujan theta function — In mathematics, the Ramanujan theta function generalizes the form of the Jacobi theta functions, while capturing their general properties. In particular, the Jacobi triple product takes on a particularly elegant form when written in terms of the… …
54Psychometric function — A psychometric function describes the relationship between a parameter of a physical stimulus and the responses of a person who has to decide about a certain aspect of that stimulus. The psychometric function usually resembles a sigmoid function… …
55Signed distance function — In mathematics and applications, the signed distance function of a set S in a metric space determines how close a given point x is to the boundary of S , with that function having positive values at points x inside S , it decreases in value as x… …
56Tarski's exponential function problem — In model theory, Tarski s exponential function problem asks whether the usual theory of the real numbers together with the exponential function is decidable. Tarski had previously shown that the theory of the real numbers (without the exponential …
57Majority function — In Boolean logic, the majority function (also called the median operator) is a function from n inputs to one output. The value of the operation is false when n/2 or more arguments are false, and true otherwise. Alternatively, representing true… …
58special function — ▪ mathematics any of a class of mathematical functions (function) that arise in the solution of various classical problems of physics. These problems generally involve the flow of electromagnetic, acoustic, or thermal energy. Different… …
59Power symbol — A power symbol is a symbol indicating that a control activates or deactivates a particular device. It incorporates line and circle figures, with the arrangement informed by the function of the control. The universal power symbols are described in …
606-j symbol — Wigner s 6 j symbols were introduced by Eugene Paul Wigner in 1940, and published in 1965.They are related to Racah s W coefficientsby: egin{Bmatrix} j 1 j 2 j 3 j 4 j 5 j 6 end{Bmatrix} = ( 1)^{j 1+j 2+j 4+j 5}W(j 1j 2j 5j 4;j 3j 6).They have… …
