Equivariant formality of the little disks operad

Algebraic Topology 2026-05-26 v2 Quantum Algebra

Abstract

The little nn-disks operad is SO(n)SO(n) and O(n)O(n)-equivariantly formal over the rationals. Equivalently, the oriented and unoriented framed little disks operads are rationally formal as \infty-operads.
