Periodic random attractors for stochastic Navier-Stokes equations on unbounded domains

Electronic Journal of Differential Equations, 2012
This article concerns the asymptotic behavior of solutions to the two-dimensional Navier-Stokes equations with both non-autonomous deterministic and stochastic terms defined on unbounded domains.

Nonassociative Algebras: A Framework for Differential Geometry

International Journal of Mathematics and Mathematical Sciences, 2003
A nonassociative algebra endowed with a Lie bracket, called a torsion algebra, is viewed as an algebraic analog of a manifold with an affine connection.

From Gauge Anomalies to Gerbes and Gerbal Representations: Group Cocycles in Quantum Theory

Acta Polytechnica, 2010
In this paper I shall discuss the role of group cohomology in quantum mechanics and quantum field theory. First, I recall how cocycles of degree 1 and 2 appear naturally in the context of gauge anomalies.

Extremal cocycles of weyl groups

Functional Analysis and Its Applications, 1987
In almost all problems in the representation theory of reductive Lie algebras one meets extremal equations (that is, equations in the ``highest vector''). In this article we consider extremal equations in a wide class of modules similar to the ``universal modules'' of Verma. A wider program of the study of such equations and related objects (Mickelsson

Scalar field on a higher-spin background via Fedosov quantization

Journal of High Energy Physics
Conformal higher-spin gravity is the log-divergent part of the effective action of the scalar field coupled to background fields via higher-spin currents, as was defined by Segal and Tseytlin, which can be worked out over the flat space background.

Geometry of Torsion Gerbes and Flat Twisted Vector Bundles

Axioms
Gerbes and higher gerbes are geometric cocycles representing higher degree cohomology classes, and are attracting considerable interest in differential geometry and mathematical physics.

CONTINUITY OF MEASURABLE COCYCLES

The Journal of Symbolic Logic
Suppose $G\curvearrowright X$ is a Polish group action, $H$ is a Polish group and $G\times X\oversetψ\longrightarrow H$ is a cocycle that is continuous in the second variable. If $ψ$ is either Baire measurable or is $λ\times μ$-measurable with respect to a Haar measure $λ$ on $G$ and a fully supported $σ$-finite Borel measure $μ$ on $X$, then $ψ$ is ...
