The $p$-adic Shintani cocycle [PDF]

, 2012
The Shintani cocycle on $\GL_n(\Q)$, as constructed by Hill, gives a cohomological interpretation of special values of zeta functions for totally real fields of degree $n$. We give an explicit criterion for a specialization of the Shintani cocycle to be $

Zeta Functions and the (Linear) Logic of Markov Processes [PDF]

Logical Methods in Computer Science
The author introduced models of linear logic known as ''Interaction Graphs'' which generalise Girard's various geometry of interaction constructions. In this work, we establish how these models essentially rely on a deep connection between zeta functions

Cocycles and Almost Periodicity [PDF]

Journal of the London Mathematical Society, 1987
Let G be a compact abelian group containing, as a dense subgroup, the image of \({\mathbb{R}}\) by a continuous injective homomorphism, say \(\alpha\). A cocycle on G is defined here as a unitary \((=\) of modulus 1) continuous function on \(G\times {\mathbb{R}}\) satisfying the identity \(Y(g,s+t)=Y(g,s)Y(g+\alpha (s),t)\). A cocycle is called trivial

AF-equivalence relations and their cocycles

, 2001
After a review of some of the main results about hyperfinite equivalence relations and their cocycles in the measured setting, we give a definition of a topological AF-equivalence relation.

Dynamics and the Cohomology of Measured Laminations

Mathematics, 2016
In this paper, the interconnection between the cohomology of measured group actions and the cohomology of measured laminations is explored, the latter being a generalization of the former for the case of discrete group actions and cocycles evaluated on ...

Integration of Cocycles and Lefschetz Number Formulae for Differential Operators

Symmetry, Integrability and Geometry: Methods and Applications, 2011
Let E be a holomorphic vector bundle on a complex manifold X such that dim_C X=n. Given any continuous, basic Hochschild 2n-cocycle ψ_{2n} of the algebra Diffn of formal holomorphic differential operators, one obtains a 2n-form f_{E,ψ_{2n}}(D) from any ...
