Morse Theory is a pivotal concept in differential topology, connecting smooth functions on manifolds with their topological aspects. It examines critical points and their Morse indices to understand a manifold's geometry and structure. This theory has broad applications in physics, mathematics, and technology, influencing areas such as dynamical systems, geodesics on surfaces, and medical imaging.
