Following the previous lecture, which discussed operations between categories, introduced some interesting features within a single categorically. Specifically, looked at categorical generalizations / analogues of the injectivity, surjectivity, and bijectivity, as well as (co-)products and pullbacks. Hinted at Yoneda and (co-)limits, to be covered in the next few lectures.
