term for concrete category with initial morphism for each element

60 Views Asked by At

I need a term for a concrete category over Set with a distinguished object $i,$ such that the morphisms from $i$ correspond to elements of the other objects. More formally, for every object $o$ and every element $x \in o,$ there is exactly one morphism $m_{o,x}: i \to O.$ Is this an established concept, and, if so, what is the nomenclature.

Note that the terms initial and pointed already have other meanings in category theory.

If what you're after is a concrete category where $U$ is representable, then such categories are called representably concrete.
