Shape theory (mathematics)

Shape theory is a branch of mathematics that studies the properties and classifications of shapes in a more abstract sense. It primarily deals with the concept of "shape" in topological spaces and focuses on understanding how shapes can be analyzed and compared based on their intrinsic properties, rather than their exact geometrical measurements. One of the key aspects of shape theory is the idea that two shapes can be considered equivalent if they can be continuously transformed into one another without cutting or gluing.
