Final topology : ウィキペディア英語版 | Final topology In general topology and related areas of mathematics, the final topology (or strong topology or colimit topology or inductive topology) on a set , with respect to a family of functions into , is the finest topology on ''X'' which makes those functions continuous. The dual notion is the initial topology. == Definition ==
Given a set and a family of topological spaces with functions : the final topology on is the finest topology such that each : is continuous. Explicitly, the final topology may be described as follows: a subset ''U'' of ''X'' is open if and only if is open in ''Y''''i'' for each ''i'' ∈ ''I''.
