Distance and parallelism between flats in Rn

Publikováno v: Linear Algebra and its Applications. 171:99-107

A simple matrix formula for the distance between two flats or affine spaces of ⊙R n is derived. The geometry of intersection and of the degree of parallelism of two flats is elucidated.

Spaces of closest fit

Autor: Seymour Kass

Publikováno v: Linear Algebra and its Applications. 117:93-97

A subspace of Rn is a space of closest fit for a given set of points if the sum of the squares of its distances to the points is minimal. A theorem of Ky Fan on sums of quadratic forms is used to characterize such spaces and to show that they are nes

Irreducible polynomial identities in anticommutative algebras

Autor: William G. Witthoft, Seymour Kass

Publikováno v: Proceedings of the American Mathematical Society. 26:1-9

The methods introduced by J. M. Osborn for isolating those polynomial identities worth studying in commutative algebras are here modified to yield three theorems for anticommutative algebras. The first establishes a practical criterion for the irredu
