Homology of $E_{n}$ ring spectra and iterated $\mathit{THH}$

##### Abstract

We describe an iterable construction of $\mathit{THH}$ for an ${E}_{n}$ ring spectrum. The reduced version is an iterable bar construction and its $n$th iterate gives a model for the shifted cotangent complex at the augmentation, representing reduced topological Quillen homology of an augmented ${E}_{n}$ algebra.
