112Lower tangent arc — A lower tangent arc is a rarely observable halo, an optical phenomenon appearing under and tangent to a 22° halo centred around the sun.Just like upper tangent arcs, the shape of a lower tangent arc is dependent on the altitude of the sun. As the …
113Zariski tangent space — In algebraic geometry, the Zariski tangent space is a construction that defines a tangent space, at a point P on an algebraic variety V (and more generally). It does not use differential calculus, being based directly on abstract algebra, and in… …
114Espace tangent (géométrie algébrique) — En géométrie algébrique, on peut définir la notion d espace tangent (de Zariski) sans faire (explicitement) de calcul différentiel. C est en quelque sorte une première approximation de la structure locale du schéma. Sommaire 1 Définition pour un… …
115Upper tangent arc — An upper tangent arc is a halo, an atmospheric optical phenomenon which appears over and tangent to the 22° halo centred around the sun.The shape of an upper tangent arc varies with the elevation of the sun; while the sun is low (less than… …
116Espace Tangent — L espace tangent en un point a d une variété différentielle M est un espace vectoriel qui intuitivement est l ensemble de tous les vecteurs vitesse possibles d un mobile se déplaçant (sans pouvoir la quitter) dans la variété M quand il est en a.… …

118Unit tangent bundle — In mathematics, the unit tangent bundle of a Finsler manifold ( M , || . ||), denoted by UT( M ) or simply UT M , is a fiber bundle over M given by the disjoint union:mathrm{UT} (M) := coprod {x in M} left{ v in mathrm{T} {x} (M) left| | v | {x} …
119Loss tangent — The loss tangent is a parameter of a dielectric material that quantifies its inherent dissipation of electromagnetic energy. The term refers to the tangent of the angle in a complex plane between the resistive (lossy) component of an… …
