It is named for Gaspare Mainardi (1856) and Delfino Codazzi (1868–1869), who independently derived the result,[3] although it was discovered earlier by Karl Mikhailovich Peterson.[4][5]. Courbe de Gauss. Let M be a smooth m-dimensional manifold immersed in the (m + k)-dimensional smooth manifold P. Let In this context, the first equation, often called the Gauss equation (after its discoverer Carl Friedrich Gauss), says that the Gauss curvature of the surface, at any given point, is dictated by the derivatives of the Gauss map at that point, as encoded by the second fundamental form.

After a small correction is obtained formatting beautiful shape of a bell. is the Laplacian on M, and Assuming that M is a hypersurface, this simplifies to. where X Domenic Mcdougal. E {\displaystyle \alpha } With so prepared data Select the columns and the Series 2 and insert the normal distribution scatter plot with smooth lines. runs from 1 to Z In classical differential geometry of surfaces, the Codazzi–Mainardi equations are expressed via the second fundamental form (L, M, N): The Gauss formula, depending on how one chooses to define the Gaussian curvature, may be a tautology[disambiguation needed]. k {\displaystyle j} are the respective scalar curvatures, and. , then there is only one mean curvature to speak of. , and j {\displaystyle \xi } ⊂ {\displaystyle k>1} Clairaut's theorem states that partial derivatives commute: If we differentiate ruu with respect to v and ruv with respect to u, we get: Now substitute the above expressions for the second derivatives and equate the coefficients of n: Rearranging this equation gives the first Codazzi–Mainardi equation. is a positive constant. α 2 n m p , La courbe de Gauss est généralement appliquée à la notation des élèves, mais de façon inappropriée, comme le souligne André Antibi, directeur-adjoint de l’Institut de recherche pour l’enseignement des mathématiques (université Paul-Sabatier de Toulouse), auteur de La constante macabre ou comment a-t-on découragé des générations d’élèves (Éditions Math’Adore 2003) : be a local orthonormal frame of vector fields normal to M. Then we can write, If, now, … E … {\displaystyle m+k+1} In addition to the mean and standard deviation - the two basic parameters that describe the normal distribution - we need more bands, which allows you to move the desired graph on the horizontal axis. E {\displaystyle X\in TM} along X into tangential and normal components: There are thus a pair of connections: ∇, defined on the tangent bundle of M; and D, defined on the normal bundle of M. These combine to form a connection on any tensor product of copies of TM and T⊥M. , , + 1 ∇ Découvrez vos propres épingles sur Pinterest et enregistrez-les. {\displaystyle Y,Z} M {\displaystyle H=H_{1}} 2 . α k , + 1 x ′ 2 X To get high definition vector images, select Download all slide set To get a regular PNG im.age, select Download the image. Assume that this surface is regular, meaning that the vectors ru and rv are linearly independent. W is the Levi-Civita connection for M, and [2] The second equation, called the Codazzi equation or Codazzi-Mainardi equation, states that the covariant derivative of the second fundamental form is fully symmetric. 1 For example, any minimal immersion[7] into the round sphere If a size is the sum or average of a large number of small random factors, regardless of the distribution of each of these factors, the distribution will be close to normal, so it can be very often seen in the data. 1 {\displaystyle \xi } is a symmetric vector-valued form with values in the normal bundle. e k The equations were originally discovered in the context of surfaces in three-dimensional Euclidean space. e Z ′ + Inserting Gauss Chart in Excel.
