Adjointness:

Σ X ⟶ Y X ∧ Y → Z

======= ===========
|

X → Ω Y X → (Y → Z)
|

|
||
Spectrum: Y : ℕ → Type* with e : Ω Yₙ₊₁ ≃* Yₙ.

HOMOLOGY:
|

Hₙ(X, Y) :≡? ∥ X ∧ Ω² (Y (n+2)) ∥₀ ≃ ∥ X ∧ Y n ∥₀

H : ℤ → Type* → AbGroup
|
||
- functorial in second argument
|
||
- (optional): respects pointed equivalences and pointed homotopies
