This is an introduction to the notion of adjunction from .
an abstract point of view. A systematic survey is made of various definitions
of this notion, including two definitions not recorded in the
literature. A similar survey is also made of the definitions of comonad,
which also includes new material. Finally, the relationship between the
notion of adjunction and the notion of comonad is explained through
two adjunctions involving the category of adjunctions and the category
of comonads, where the latter category is isomorphic to a full subcategory
of the former. The+ standard presentation of this relationship,
through the category of resolutions of a comonad, is a corollary of this
new presentation of the matter.
