In mathematics, Frobenius' theorem gives necessary and sufficient conditions for finding a maximal set of independent solutions of an overdetermined system of first-order homogeneous linear partial differential equations. In modern geometric terms, given a family of vector fields, the theorem gives necessary … Meer weergeven In its most elementary form, the theorem addresses the problem of finding a maximal set of independent solutions of a regular system of first-order linear homogeneous partial differential equations. Let Meer weergeven Despite being named for Ferdinand Georg Frobenius, the theorem was first proven by Alfred Clebsch and Feodor Deahna. Deahna was the first to establish the sufficient conditions for the theorem, and Clebsch developed the necessary conditions. … Meer weergeven • Integrability conditions for differential systems • Domain-straightening theorem • Newlander-Nirenberg Theorem Meer weergeven The Frobenius theorem can be restated more economically in modern language.

The identity map is a trivial example of an involution. Examples of nontrivial involutions include negation (), reciprocation (), and complex conjugation () in arithmetic; reflection, half-turn rotation, and circle inversion in geometry; complementation in set theory; and reciprocal ciphers such as the ROT13 transformation and the Beaufort polyalphabetic cipher. imvu classic sign inWebThe answer in this case is more complicated than in the case of vector fields: there is a nontrivial necessary condition, called involutivity, that must be satisfied by the distribution. In the first section of the chapter, we define involutivity and give examples of both involutive and noninvolutive distributions. dutch healthcare allowance
