Webb29 maj 2015 · The Dubovitskiï-Sard Theorem in Sobolev Spaces Piotr Hajlasz & Scott Zimmerman ABSTRACT. The Sard theorem from 1942 requires that a map ping / : Kn — IRm is of class Cfc, k > max(n - m, 0). In 1957, Duvovitskiï generalized Sard's theorem to the case of Ck mappings for all k. Specifically, he proved that, for almost all y e Km, WebbConvergence of measures. In mathematics, more specifically measure theory, there are various notions of the convergence of measures. For an intuitive general sense of what is meant by convergence of measures, consider a sequence of measures μ n on a space, sharing a common collection of measurable sets. Such a sequence might represent an ... tengu fishing derby
