Geometric topology delves into the qualitative properties of space, focusing on manifolds, knots, and the interplay between algebra and geometry. It examines how spaces can be transformed while preserving their essential properties, using concepts like homeomorphism to understand topological equivalence. The field has applications in science and technology, influencing areas such as computer science, biology, and physics, and is fundamental in the study of 2D and 3D topological spaces.
