Abstract:

We define a category, $\mathcal {H}_p^n$ (for each $n$ and $p$), of spaces with strong homotopy commutativity properties. These spaces have just enough structure to define the $\bmod p$ Dyer-Lashof operations for $n$-fold loop spaces. The category $\mathcal {H}_p^n$ is very convenient for applications since its objects and morphisms are defined in a homotopy invariant way. We then define a functor, $P_p^n$, from $\mathcal {H}_p^n$ to the homotopy category of spaces and show $P_p^n$ to be left adjoint to the $n$-fold loop space functor. We then show how one can exploit this adjointness in cohomological calculations to yield new results about iterated loop spaces.
