What do "globe", "globe category", "globular set" mean?

What's the canonical embedding of the globe category into Top?

  • They are the maps of the closed n-ball to the "northern" and "southern" hemispheres of the surface of the (n+1)-ball.
  • This defines a functor G→Top that extends along the Yoneda embedding, yielding a geometric representation of any globular set Gˆ→Top.
