Homotopy Type Theory

H-space (Rev #1)

### Definition

A H-Space consists of

- A type $A$,
- A basepoint $e:A$
- A binary operation $\mu : A \to A \to A$
- for every $a:A$, equalities $\mu(e,a)=a$ and $\mu(a,e)=a$

### Lemma

Let $A$ be a connected H-space. Then for every $a:A$, the maps $\mu(a,-),\mu(-,a):A \to A$ are equivalences.
