Loops

Definition

In Morse Theory, loops refer to continuous paths in a topological space that can return to their starting point without leaving the space. These loops play a crucial role in understanding the structure and features of spaces, particularly in relation to homotopy and how these paths can be deformed within the space. Analyzing loops helps in visualizing complex topological properties and is essential for computational aspects, including algorithms that study these features.
