Cocycles, Symplectic Structures and Intersection

open access: yesGeometric And Functional Analysis, 1999
We investigate the cross ratio for closed negatively curved manifolds. As one of several applications, we obtain that for two such homotopy equivalent manifolds M and N, the following is true : If M and N have the same marked length spectrum and if the Anosov splitting for M is C^1 then M and N have the same volume.

Extremal cocycles of weyl groups

open access: yesFunctional 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

CONTINUITY OF MEASURABLE COCYCLES

open access: yesThe 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 ...

BRST Noether theorem and corner charge bracket

open access: yesJournal of High Energy Physics
We provide a proof of the BRST Noether 1.5th theorem, conjectured in [ JHEP 10 (2024) 055 ], for a broad class of rank-1 BV theories including supergravity and 2-form gauge theories. The theorem asserts that the BRST Noether current of any BRST invariant

Continuous bounded cocycles

open access: yes, 2011
Let $G$ be a minimal locally compact groupoid with compact metrizable unit space and let $E$ be a continuous $G$-Hilbert bundle. We show that a bounded continuous cocycle $c: G\ra r^*E$ is necessarily a continuous coboundary. This is a groupoid version of a classical theorem of Gottschalk and Hedlund.
