Invariant based programming — is a programming methodology where specifications and invariants are written before the actual program statements. Writing down the invariants during the programming process has a number of advantages: it requires the programmer to make his… … Wikipedia
Invariant estimator — In statistics, the concept of being an invariant estimator is a criterion that can be used to compare the properties of different estimators for the same quantity. It is a way of formalising the idea that an estimator should have certain… … Wikipedia
Invariant (physics) — In mathematics and theoretical physics, an invariant is a property of a system which remains unchanged under some transformation.The gravitational field of the Sun is invariant under a change of time (from, say, now to tomorrow). It is also… … Wikipedia
Class invariant — This article is about class invariants in computer programming, for use of the term in mathematics, see equivalence class and invariant. In computer programming, specifically object oriented programming, a class invariant is an invariant used to… … Wikipedia
Casson invariant — In 3 dimensional topology, a part of the mathematical field of geometric topology, the Casson invariant is an integer valued invariant of oriented integral homology 3 spheres, introduced by Andrew Casson.Kevin Walker (1992) found an extension to… … Wikipedia

Colin de Verdière graph invariant — Colin de Verdière s invariant is a graph parameter μ(G) for any graph G introduced by Yves Colin de Verdière in 1990. It was motivated by the study of the maximum multiplicity of the second eigenvalue of certain Schrödinger operators.[1] Contents … Wikipedia
Knot invariant — In the mathematical field of knot theory, a knot invariant is a quantity (in a broad sense) defined for each knot which is the same for equivalent knots. The equivalence is often given by ambient isotopy but can be given by homeomorphism. Some… … Wikipedia
Writer invariant — Writer invariant, also called authorial invariant or author s invariant, is property of a text which is invariant of its author, that is, it will be similar in all texts of a given author and different in texts of different authors. It can be… … Wikipedia
Geometric invariant theory — In mathematics Geometric invariant theory (or GIT) is a method for constructing quotients by group actions in algebraic geometry, used to construct moduli spaces. It was developed by David Mumford in 1965, using ideas from the paper… … Wikipedia
