# The homology of the little disks operad

@article{Sinha2006TheHO, title={The homology of the little disks operad}, author={Dev P. Sinha}, journal={arXiv: Algebraic Topology}, year={2006} }

In this expository paper we give an elementary, hands-on computation of the homology of the little disks operad, showing that the homology of a $d-fold loop space is a Poisson algebra. One aim is to familiarize a greater audience with Euclidean configuration spaces, using tools accessible to second-year graduate students. We also give a brief introduction to the theory of operads. New results include identifying the pairing between homology and cohomology of these spaces as a pairing of graphs…

A Geometric Homology Representative in the Space of Long Knots

- Mathematics
- 2011

We produce explicit geometric representatives of nontrivial homology classes in the space of long knots in R^d, when d is even. We generalize results of Cattaneo, Cotta-Ramusino and Longoni to define…

Graph-complexes computing the rational homotopy of high dimensional analogues of spaces of long knots

- Mathematics

We continue our investigation of spaces of long embeddings (long embeddings are high-dimensional analogues of long knots). In previous work we showed that when the dimensions are in the stable range,…

A pairing between graphs and trees

We develop a canonical pairing between trees and graphs, which passes to their quotients by Jacobi identities. This pairing is an effective and simple tool for understanding the Lie and Poisson…

Cohomology of Polychromatic Configuration Spaces of Euclidean Space
