projective function
11Duality (projective geometry) — A striking feature of projective planes is the symmetry of the roles played by points and lines in the definitions and theorems, and (plane) duality is the formalization of this metamathematical concept. There are two approaches to the subject of …
12Wave function — Not to be confused with the related concept of the Wave equation Some trajectories of a harmonic oscillator (a ball attached to a spring) in classical mechanics (A B) and quantum mechanics (C H). In quantum mechanics (C H), the ball has a wave… …
13Real projective line — In real analysis, the real projective line (also called the one point compactification of the real line, or the projectively extended real numbers ), is the set mathbb{R}cup{infty}, also denoted by widehat{mathbb{R and by mathbb{R}P^1.The symbol… …
14Limit of a function — x 1 0.841471 0.1 0.998334 0.01 0.999983 Although the function (sin x)/x is not defined at zero, as x becomes closer and closer to zero, (sin x)/x becomes arbitrarily close to 1. It is said that the limit of (sin x)/x as x approache …
15Partition function (mathematics) — The partition function or configuration integral, as used in probability theory, information science and dynamical systems, is an abstraction of the definition of a partition function in statistical mechanics. It is a special case of a… …
16Real projective plane — In mathematics, the real projective plane is the space of lines in R3 passing through the origin. It is a non orientable two dimensional manifold, that is, a surface, that has basic applications to geometry, but which cannot be embedded in our… …
17Local zeta-function — In number theory, a local zeta function is a generating function : Z ( t ) for the number of solutions of a set of equations defined over a finite field F , in extension fields Fk of F . FormulationThe analogy with the Riemann zeta function… …
18Wave function collapse — Quantum mechanics Uncertainty principle …
19Rate function — In mathematics mdash; specifically, in large deviations theory mdash; a rate function is a function used to quantify the probabilities of rare events. It is required to have several nice properties which assist in the formulation of the large… …
20Iterated function system — In mathematics, iterated function systems or IFSs are a method of constructing fractals; the resulting constructions are always self similar.IFS fractals as they are normally called can be of any number of dimensions, but are commonly computed… …
