Voiculescu Theorem, Sobolev Lemma, and Extensions of Smooth Algebras
We present the analytic foundation of a unified B-D-F extension functor Extr on the category of noncommutative smooth algebras, for any Fréchet operator ideal ^ . Combining the techniques devised by Arveson and Voiculescu, we generalize Voiculescu's theorem to smooth algebras and Fréchet operator ideals. A key notion involved is r-smoothness, which is verified for the algebras of smooth functio...
متن کاملAn Abstract Regularity Lemma
We extend in a natural way Szemerédis Regularity Lemma to abstract measure spaces. 1 Introduction In this note we extend Szemerédis Regularity Lemma (SRL) to abstract measure spaces. Our main aim is to nd general conditions under which the original proof of Szemerédi still works. Another extension of SRL to probality spaces was proved by Tao [3], but his results do not imply our most general...
متن کاملAn Approach to Hensel's Lemma
Hensel's Lemma is an important tool in many ways. One application is in factoring polynomials over Z. The computation in applying Hensel's Lemma proceeds by using the Euclidean algorithm. In this short article we present another approach to Hensel's Lemma, and we show that the lift of a polynomial can be calculated in another way. In some cases this is computationally faster. The proof is a con...
متن کاملAN INVERSE PROBLEM WITH UNKNOWN RADIATION TERM
In this paper, we consider an inverse problem of linear heat equation with nonlinear boundary condition. We identify the temperature and the unknown radiation tern from an overspecified condition on the boundary
