This page will attempt to list examples in mathematics. To qualify for inclusion, an article should be about a mathematical object with a fair amount of concreteness. Usually a definition of an abstract concept, a theorem, or a proof would not be an "example" as the term should be understood here (an elegant proof of an isolated but particularly striking fact, as opposed to a proof of a ...
Java library implementing Allen's Interval Algebra (incl. data and index structures, e.g., interval tree) OWL-Time Time Ontology in OWL an OWL-2 DL ontology of temporal concepts, for describing the temporal properties of resources in the world or described in Web pages. GQR is a reasoner for Allen's interval algebra (and many others)
The Jiffy is the amount of time light takes to travel one femtometre (about the diameter of a nucleon). The Planck time is the time that light takes to travel one Planck length. The TU (for time unit) is a unit of time defined as 1024 μs for use in engineering. The svedberg is a time unit used for sedimentation rates (usually
The main objective of interval arithmetic is to provide a simple way of calculating upper and lower bounds of a function's range in one or more variables. These endpoints are not necessarily the true supremum or infimum of a range since the precise calculation of those values can be difficult or impossible; the bounds only need to contain the function's range as a subset.
Discrete calculus or the calculus of discrete functions, is the mathematical study of incremental change, in the same way that geometry is the study of shape and algebra is the study of generalizations of arithmetic operations.
An interval is said to be bounded, if it is both left- and right-bounded; and is said to be unbounded otherwise. Intervals that are bounded at only one end are said to be half-bounded. The empty set is bounded, and the set of all reals is the only interval that is unbounded at both ends. Bounded intervals are also commonly known as finite ...
Each date can include an era or a time, and a variety of formats are accepted. Examples of valid dates are: 1900-02-01 1900-2-1 1900-02-01 14:45 1 FEB 1900 February 1, 1900 February 1 1900 14:45 2:45 pm February 1 1900 1 February 1900 2:45 p.m. BC 1 Feb 120. Examples: {{time interval|1 Jan 2001|March 4, 2002}} → 1 year, 2 months and 3 days
The primary vehicle of calculus and other higher mathematics is the function. Its "input value" is its argument , usually a point ("P") expressible on a graph. The difference between two points, themselves, is known as their Delta (Δ P ), as is the difference in their function result, the particular notation being determined by the direction ...
