81Geodesic (general relativity) — This article is about the use of geodesics in general relativity. For the general concept in geometry, see geodesic. General relativity Introduction Mathematical formulation Resources …
82Cauchy's integral formula — In mathematics, Cauchy s integral formula, named after Augustin Louis Cauchy, is a central statement in complex analysis. It expresses the fact that a holomorphic function defined on a disk is completely determined by its values on the boundary… …
83Geodesic — [ great circle arcs.] In mathematics, a geodesic IPA|/ˌdʒiəˈdɛsɪk, ˈdisɪk/ [jee uh des ik, dee sik] is a generalization of the notion of a straight line to curved spaces . In presence of a metric, geodesics are defined to be (locally) the… …
84Tired light — is a class of hypothetical redshift mechanisms that were proposed as an alternative explanation for the redshift distance relationship as alternatives to the Big Bang and the Steady State cosmologies, both of which proposed that Hubble s law was… …
85Hilbert's Theorem 90 — In number theory, Hilbert s Theorem 90 (or Satz 90) refers to an important result on cyclic extensions of number fields (or to one of its generalizations) that leads to Kummer theory. In its most basic form, it tells us that if L / K is a cyclic… …
86Soil mechanics — is a discipline that applies principles of engineering mechanics, e.g. kinematics, dynamics, fluid mechanics, and mechanics of material, to predict the mechanical behavior of soils. Together with Rock mechanics, it is the basis for solving many… …
87Einstein synchronisation — (or Einstein Poincaré synchronisation) is a convention in relativity for synchronizing clocks at different places.PoincaréIn the framework of Lorentz ether theory, it was stated by Henri Poincaré in 1900 that 2 observers A and B which are moving… …
88Non-negative matrix factorization — NMF redirects here. For the bridge convention, see new minor forcing. Non negative matrix factorization (NMF) is a group of algorithms in multivariate analysis and linear algebra where a matrix, , is factorized into (usually) two matrices, and… …
89Round function — In topology and in calculus, a round function is a scalar function , over a manifold M, whose critical points form one or several connected components, each homeomorphic to the circle S1, also called critical loops. They are special cases of… …
