A continuous map is a function between two topological spaces that preserves the notion of closeness, meaning that the preimage of every open set in the target space is an open set in the domain space. This property ensures that small changes in the input lead to small changes in the output, establishing a consistent relationship between the two spaces. Continuous maps are essential in various branches of mathematics, particularly in topology and analysis, where they facilitate the study of spatial properties and transformations.
