Formally, a diagram of shape $${\displaystyle J}$$ in $${\displaystyle C}$$ Se mer Limits The definition of limits is general enough to subsume several constructions useful in practical settings. In the following we will consider the limit (L, φ) of a diagram F : J → C. • Se mer Older terminology referred to limits as "inverse limits" or "projective limits", and to colimits as "direct limits" or "inductive limits".
