Parallel transport — In geometry, parallel transport is a way of transporting geometrical data along smooth curves in a manifold. If the manifold is equipped with an affine connection (a covariant derivative or connection on the tangent bundle), then this connection… … Wikipedia
Curvature — In mathematics, curvature refers to any of a number of loosely related concepts in different areas of geometry. Intuitively, curvature is the amount by which a geometric object deviates from being flat, or straight in the case of a line, but this … Wikipedia
Parallel (geometry) — Parallelism is a term in geometry and in everyday life that refers to a property in Euclidean space of two or more lines or planes, or a combination of these. The assumed existence and properties of parallel lines are the basis of Euclid s… … Wikipedia
Parallel curve — An ellipse (red), its evolute (blue) and some parallel curves (green). Note how the parallel curves have cusps when they touch the evolute … Wikipedia
Radius of curvature (applications) — The distance from the center of a sphere or ellipsoid to its surface is its radius. The equivalent surface radius that is described by radial distances at points along the body s surface is its radius of curvature (more formally, the radius of… … Wikipedia
Circle of curvature — Circle Cir cle (s[ e]r k l), n. [OE. cercle, F. cercle, fr. L. circulus (Whence also AS. circul), dim. of circus circle, akin to Gr. kri kos, ki rkos, circle, ring. Cf. {Circus}, {Circum }.] [1913 Webster] 1. A plane figure, bounded by a single… … The Collaborative International Dictionary of English
Instantaneous Center of Curvature — Bei einem mit Rädern angetriebenen Objekt müssen sich alle Achsen im Momentanpol M treffen, damit eine Bewegung möglich ist. Als rote Pfeile sind die Geschwindigkeitsvektoren der Hinterachsräder eingezeichnet. Bei einem Momentanpol handelt es… … Deutsch Wikipedia
center of parallel wheel motion — the center of curvature of the path along which each of a pair of wheel centers moves in a longitudinal vertical plane relative to the sprung mass when both wheels are equally displaced … Mechanics glossary
David Allen Hoffman — (* 21. Juli 1944 in Far Rockaway, Queens, New York)[1] ist ein US amerikanischer Mathematiker, der sich mit Differentialgeometrie und speziell Minimalflächen beschäftigt. Hoffman studierte an der University of Rochester (Bachelor 1966) und an der … Deutsch Wikipedia
Positive Butterfly — A non parallel yield curve shift in which short and long term rates shift upward by a greater magnitude than medium term rates. This yield curve shift effectively humps the curve, adding to its curvature. A non parallel shift in the yield curve… … Investment dictionary
Holonomy — Parallel transport on a sphere depends on the path. Transporting from A → N → B → A yields a vector different from the initial vector. This failure to return to the initial vector is measured by the holonomy of the connection. In differential… … Wikipedia
