Historically, the method of least squares was used by Gauss and Legendre to solve problems in astronomy and geodesy. The method was first published by Legendre in 1805 in a paper on methods for determining the orbits of comets. However, Gauss had al

For example, the group .(.) of rotations is the group of orientation-preserving isometries of the Euclidean space .. The Lie algebra . (.,?) consisting of real skew symmetric . × . m

Almost all of the material presented in this chapter is based on lectures given by Eugenio Calabi in an upper undergraduate differential geometr

Tohru Nakamura,Yukio Hama,Mohamed ZakariaIn affine geometry it is possible to deal with ratios of vectors and barycenters of points, but there is no way to express the notion of length of a line segment or to talk about orthogonality of vectors. A Euclidean structure allows us to deal with . such as orthogonality and length (or distance).
