delooping of the additive monoid of ordinal numbers

Notation BOnB\OnColl Objects a single object Morphisms ordinal numbers, with addition as composition Related BNB\IN
Every monoid MM induces a category BMBM with a single object ∗*. This also works when MM is large, in which case BMBM is not locally small. In this example, we apply this construction to the large monoid of ordinal numbers with respect to addition, so composition is α∘β=α+β\alpha \circ \beta = \alpha + \beta.
