| Abstract: | A notion of compactness with respect to a previously introduced notion of functor induced closure operator is presented and
analyzed. Even though this new notion shows very similar properties to compactness with respect to the classical notion of
categorical closure operator, in general the two concepts are different. Examples are provided. |
