Idea
Generally, an inductive limit is the same thing as a colimit . (Similarly, a projective limit is the same thing as a limit .) In this context, an inductive system is the same thing as a diagram , and an inductive cone is the same thing as a cocone .

However, many authors restrict this terminology to colimits over directed sets (or filtered categories ), especially the directed set $(\mathbb{N},\leq)$ of natural numbers ; see directed colimit (or filtered colimit ) for discussion of this case if you think that it may be what you want.

The dual concept is that of a projective limit .
