Coformality and the rational homotopy groups of spaces of long knots
arXiv:math/0701350
Abstract
We show that the Bousfield-Kan spectral sequence which computes the rational homotopy groups of the space of long knots in , where , collapses at the page. The main ingredients in the proof are Sinha's cosimplicial model for the space of long knots and a coformality result for the little balls operad.
