In structured-types.h-spaces we saw that the type of H-space structures on a pointed type A is equivalently described as the type of pointed sections of the pointed evaluation map (A → A) →∗ A. If the type A is connected, then the section maps to the connected component of (A ≃ A) at the identity equivalence. An evaluative H-space is a pointed type such that the map ev_pt : (A ≃ A)_{(id)} → A is an equivalence.
