Algebraic structures on graph cohomology

Alberto S. Cattaneo, Paolo Cotta-Ramusino, Riccardo Longoni

We define algebraic structures on graph cohomology and prove that they correspond to algebraic structures on the cohomology of the spaces of imbeddings of S^1 or R into R^n. As a c…

On the AKSZ formulation of the Poisson sigma model

Alberto S. Cattaneo, Giovanni Felder

We review and extend the Alexandrov-Kontsevich-Schwarz-Zaboronsky construction of solutions of the Batalin-Vilkovisky classical master equation. In particular, we study the case of…

Loop observables for BF theories in any dimension and the cohomology of knots

Alberto S. Cattaneo, Paolo Cotta-Ramusino, Carlo A. Rossi

A generalization of Wilson loop observables for BF theories in any dimension is introduced in the Batalin-Vilkovisky framework. The expectation values of these observables are coho…

Configuration space integrals and invariants for 3-manifolds and knots

Alberto S. Cattaneo

The first part of this paper is a short review of the construction [dg-ga/9710001] of invariants of rational homology 3-spheres and knots in terms of configuration space integrals.…

Integral Invariants of 3-Manifolds

R. Bott, A. S. Cattaneo

This note describes an invariant of rational homology 3-spheres in terms of configuration space integrals which in some sense lies between the invariants of Axelrod and Singer and…
