Web18 de out. de 2014 · The first result free of this shortcoming was due to A. Baker (1967). Effective proofs of Siegel's theorem have been obtained for various classes of Diophantine equations, but in the general case the problem is still open (see ). Another important problem is to generalize Siegel's theorem to varieties of dimension greater than one. … Web4 de set. de 2009 · We present a uniformization of Reeken’s macroscopic differentiability (see [5]), discuss its relations to uniform differentiability (see [6]) and classical continuous differentiability, prove the corresponding chain rule, Taylor’s theorem, mean value theorem, and inverse mapping theorem.
