Abstract
We study the \((\infty , 1)\)-category of autoequivalences of \(\infty \)-operads. Using techniques introduced by Toën, Lurie, and Barwick and Schommer-Pries, we prove that this \((\infty , 1)\)-category is a contractible \(\infty \)-groupoid. Our calculation is based on the model of complete dendroidal Segal spaces introduced by Cisinski and Moerdijk. Similarly, we prove that the \((\infty , 1)\)-category of autoequivalences of non-symmetric \(\infty \)-operads is the discrete monoidal category associated to \(\mathbf {Z}/2\mathbf {Z}\). We also include a computation of the \((\infty ,1)\)-category of autoequivalences of \((\infty , n)\)-categories based on Rezk’s \(\Theta _n\)-spaces.
