In algebraic geometry and related fields, a **quasi-compact morphism** is a type of morphism of schemes or topological spaces that relates to the compactness of the images of certain sets. A morphism of schemes \\( f: X \\to Y \\) is called **quasi-compact** if the preimage of every quasi-compact subset of \\( Y \\) under \\( f \\) is quasi-compact in \\( X \\).
