  • Differential geometry of surfaces — Carl Friedrich Gauss in 1828 In mathematics, the differential geometry of surfaces deals with smooth surfaces with various additional structures, most often, a Riemannian metric. Surfaces have been extensively studied from various perspectives:… …   Wikipedia

  • Gaussian curvature — In differential geometry, the Gaussian curvature or Gauss curvature of a point on a surface is the product of the principal curvatures, κ 1 and κ 2, of the given point. It is an intrinsic measure of curvature, i.e., its value depends only on how… …   Wikipedia

  • Contact (mathematics) — Osculation redirects here. For other meanings, see Kiss. In mathematics, contact of order k of functions is an equivalence relation, corresponding to having the same value at a point P and also the same derivatives there, up to order k. The… …   Wikipedia

  • Germ (mathematics) — In mathematics, the notion of a germ of an object in/on a topological space captures the local properties of the object. In particular, the objects in question are mostly functions (or maps) and subsets. In specific implementations of this idea,… …   Wikipedia

  • Principal curvature — Saddle surface with normal planes in directions of principal curvatures In differential geometry, the two principal curvatures at a given point of a surface are the eigenvalues of the shape operator at the point. They measure how the surface… …   Wikipedia

  • Cusp (singularity) — An ordinary cusp on the curve x3–y2=0 In the mathematical theory of singularities a cusp is a type of singular point of a curve. Cusps are local singularities in that they are not formed by self intersection points of the curve. The plane curve… …   Wikipedia

  • Meusnier's theorem — In differential geometry, Meusnier s theorem states that all curves on a surface passing through a given point p and having the same tangent line at p also have the same normal curvature at p and their osculating circles form a sphere. The… …   Wikipedia

  • Oval (Geometrie) — Oval mit einer Symmetrieachse Der Begriff Oval (lat. ovum = Ei) bezeichnet eine ebene rundliche konvexe Figur, die im weitesten Sinne dem Profil eines Vogeleis ähnelt. Sie umfasst Kreise und Ellipsen als Spezialfälle, wobei ein beliebiges Oval im …   Deutsch Wikipedia

  • Точка округления — (круговая точка, омбилическая точка или омбилика; название «омбилика» происходит от лат. «umbilicus» ― «пуп») ― точка на гладкой регулярной поверхности в евклидовом пространстве, в которой нормальные кривизны по всем направлениям равны.… …   Википедия

  • Complex plane — Geometric representation of z and its conjugate in the complex plane. The distance along the light blue line from the origin to the point z is the modulus or absolute value of z. The angle φ is the argument of z. In mathematics …   Wikipedia
