91Determinant — This article is about determinants in mathematics. For determinants in epidemiology, see Risk factor. In linear algebra, the determinant is a value associated with a square matrix. It can be computed from the entries of the matrix by a specific… …
92Métrica de Reissner-Nordström — La métrica de Reissner Nordström es una solución exacta con simetría esférica de las ecuaciones de Einstein que describe el campo gravitatorio y electromagnético de un cuerpo masivo con carga neta diferente de cero. Puede considerarse como la… …
93Lorentz covariance — In standard physics, Lorentz covariance is a key property of spacetime that follows from the special theory of relativity, where it applies globally. Local Lorentz covariance refers to Lorentz covariance applying only locally in an infinitesimal… …
94Cartan connection applications — This page covers applications of the Cartan formalism. For the general concept see Cartan connection.Vierbeins, et cetera The vierbein or tetrad theory much used in theoretical physics is a special case of the application of Cartan connection in… …
95Newman-Penrose formalism — The Newman Penrose Formalism is a set of notation developed by Ezra T. Newman and Roger Penrose [cite journal | author= Ezra T. Newman and Roger Penrose | title=An Approach to Gravitational Radiation by a Method of Spin Coefficients |… …
96Newman–Penrose formalism — The Newman Penrose Formalism is a set of notation developed by Ezra T. Newman and Roger Penrose[1] for General Relativity. Their notation is an effort to treat General Relativity in terms of spinor notation, which introduces complex forms of the… …

98Gauss's lemma (Riemannian geometry) — In Riemannian geometry, Gauss s lemma asserts that any sufficiently small sphere centered at a point in a Riemannian manifold is perpendicular to every geodesic through the point. More formally, let M be a Riemannian manifold, equipped with its… …
99Суперквадрики — Примеры суперквадриков Суперквадрики  семейство геометрических поверхностей, определяемых уравнением эллипсоида и других поверхностей второго порядка, где показатели степени 2 заменены произвольным числом. Их можно считать трёхмерными… …
100Krummlinige Koordinaten — Es gibt zwei bekannte und gebräuchliche Darstellungen von Vektoren in krummlinigen Koordinaten, die beide zu den orthogonalen Koordinatensystemen zählen: ebene Polarkoordinaten (2D) bzw. deren 3 dimensionale Entsprechung, die Zylinderkoordinaten… …
