WebEnescu which discusses the action of the Frobenius on finite dimensional vector spaces both of which are related to tight closure. Finiteness properties of rings and modules or the lack of them come up in all aspects of commutative algebra. However, in the study of non-noetherian rings it is much easier to WebThe Frobenius norm is an extension of the Euclidean norm to and comes from the Frobenius inner product on the space of all matrices. The Frobenius norm is sub-multiplicative and is very useful for numerical linear algebra. The sub-multiplicativity of Frobenius norm can be proved using Cauchy–Schwarz inequality.

WebWhat is the Method of Frobenius? 1. The method of Frobenius works for differential equations of the form y00 +P(x)y0 +Q(x)y=0 in which P or Q is not analytic at the point of expansion x 0. 2. But P and Q cannot be arbitrary: (x−x 0)P(x) and (x−x 0)2Q(x) must be analytic at x 0. 3. Instead of a series solution y= ∞ ∑ n=0 c n(x−x 0)n ...
