Let \(R\) be a von Neumann algebra and \(S\) be a unital dual Banach \(R\)-bimodule. A bounded bilinear mapping \(\Phi\colon R\times R\to S\) is called a local \(2\)-cocycle if, for each pair \((a,b)\in R\times R\), there exists a bounded bilinear mapping \(\Phi_{a,b}\colon R\times R\to S\) such that \(\Phi(a,b)=\Phi_{a,b}(a,b)\) and \(\Phi_{a,b ...

Classical and Quantum Gravity, 1986
Preservation of Weyl invariance at the quantum level is a widely accepted consistency criterion for classically conformally invariant field theories. The paper determines the purely gravitational part of the Weyl anomalies in six dimensions by a purely cohomological method that identifies the anomalies with 1-cocycles of a certain coboundary operator ...

Mathematische Zeitschrift, 2000
The author deals with the cocyclic subshifts which can be considered as a generalization of sofic systems introduced by B. Weiss. The main goal of the author is to prove that the topologically transitive cocyclic subshifts are intrinsically ergodic, that is have a unique invariant probability measure of maximal entropy.

Journal of the London Mathematical Society, 1985
The author strengthens a result of \textit{K. Schmidt} [Cocycles on ergodic transformation groups (1977; Zbl 0421.28017.)] providing a sufficient condition for an additive real measurable cocycle to be a coboundary. The paper under review deals with the general case while the result of Schmidt treates the ergodic one.

UHF flows are the flows obtained as inductive limits of flows on full matrix algebras. We will revisit universal UHF flows and give an explicit construction of such flows on a UHF algebra Mk∞ for any k and also present a characterization of such flows. Those flows are UHF flows whose cocycle perturbations are almost conjugate to themselves.
