Coformality and the rational homotopy groups of spaces of long knots

Gregory Arone, Pascal Lambrechts, Victor Tourtchine +1

We show that the Bousfield-Kan spectral sequence which computes the rational homotopy groups of the space of long knots in ${\mathbb{R}}^d$, where $d\ge 4$, collapses at the $E^2$ p…
