Topological structure

Definition

Topological structure refers to the properties of a space that are preserved under continuous transformations, emphasizing how objects are connected rather than their specific geometric form. This concept is crucial when analyzing complex shapes, such as those found in biomolecules, as it reveals the underlying arrangement and connectivity within the structure, impacting their functionality and interactions.
