Let R be a real AW
*-algebra, and suppose that its complexification M = R + iR is also a (complex) AW
*-algebra. We prove that R is of type I if and only if so is M.Translated from Funktsionalnyi Analiz i Ego Prilozheniya, Vol. 38, No. 4, pp. 79–81, 2004Original Russian Text Copyright © by Sh. A. Ayupov 相似文献

This paper is devoted to derivations on the algebra S 0(M, τ) of all τ-compact operators affiliated with a von Neumann algebra M and a faithful normal semi-finite trace τ. The main result asserts that every t τ -continuous derivation ${D : S_0(M, \tau) \rightarrow S_{0}(M, \tau)}$ is spatial and implemented by a τ-measurable operator affiliated with M, where t τ denotes the measure topology on S 0(M, τ). We also show the automatic t τ -continuity of all derivations on S 0(M, τ) for properly infinite von Neumann algebras M. Thus in the properly infinite case the condition of t τ -continuity of the derivation is redundant for its spatiality. 相似文献

The paper is devoted to so-called local and 2-local derivations on the noncommutative Arens algebra L ω(M,τ) associated with a von Neumann algebra M and a faithful normal semi-finite trace τ. We prove that every 2-local derivation on L ω(M,τ) is a spatial derivation, and if M is a finite von Neumann algebra, then each local derivation on L ω(M,τ) is also a spatial derivation and every 2-local derivation on M is in fact an inner derivation. 相似文献

A survey of recent results in classification of JW-algebras (weakly closed Jordan algebras of self-adjoint operators in the Hilbert space) is given along with connections of JW-algebras with their enveloping W*-algebras. It is shown how these results are applied in the proofs of analogs of many important results in the theory of W*-algebras.Translated from Itogi Nauki i Tekhniki, Seriya Sovremennye Problemy Matematiki (Noveishie Dostizheniya), Vol. 27, pp. 67–98, 1985. 相似文献

Polycrystalline rutile films are synthesized on fused quartz substrates by the method of thermal oxidation of a titanium metal
layer in air at 800°C. The optical parameters of the TiO
2 films are determined for a wavelength of λ = 0.6328 μm by the method of laser zero ellipsometry.
