one-variable function
61Covariance function — In probability theory and statistics, covariance is a measure of how much two variables change together and the covariance function describes the variance of a random variable process or field. For a random field or stochastic process Z(x) on a… …
62Bump function — In mathematics, a bump function is a function f: {Bbb R}^n o {Bbb R} on a Euclidean space {Bbb R}^n which is both smooth (in the sense of having continuous derivatives of all orders) and compactly supported. The space of all bump functions on… …
63Linear function — In mathematics, the term linear function can refer to either of two different but related concepts.Analytic geometryIn analytic geometry, the term linear function is sometimes used to mean a first degree polynomial function of one variable. These …
64Correlation function (astronomy) — For other uses, see Correlation function (disambiguation). Physical cosmology …
65p-adic L-function — In mathematics, a p adic zeta function, or more generally a p adic L function, is a function analogous to the Riemann zeta function, or more general L functions, but whose domain and target are p adic (where p is a prime number). For example, the …
66Elementary function — This article discusses the concept of elementary functions in differential algebra. For simple functions see the list of mathematical functions. For the concept of elementary form of an atom see oxidation state. In mathematics, an elementary… …
67Hamilton's principal function — The Hamilton s principal function is defined by the Hamilton–Jacobi equation (HJE), another alternative formulation of classical mechanics. This function S is related to the usual action, mathcal{S}, by fixing the initial time t {1} and endpoint… …
68Regular function — In complex analysis, see holomorphic function. In mathematics, a regular function in the sense of algebraic geometry is an everywhere defined, polynomial function on an algebraic variety V with values in the field K over which V is defined. For… …
69Graph of a function — In mathematics, the graph of a function f is the collection of all ordered pairs ( x , f ( x )). In particular, if x is a real number, graph means the graphical representation of this collection, in the form of a curve on a Cartesian plane,… …
70Computable real function — In mathematical logic, specifically computability theory, a function is sequentially computable if, for every computable sequence of real numbers, the sequence is also computable. A function is effectively uniformly continuous if there exists a… …
