Topology Rubber Sheet Geometry

A circle made out of a rubber band can be stretched into a square.

Topology rubber sheet geometry.

Topology branch of mathematics sometimes referred to as rubber sheet geometry in which two objects are considered equivalent if they can be continuously deformed into one another through such motions in space as bending twisting stretching and shrinking while disallowing tearing apart or gluing together parts. A circle can be stretched into a square with a rubber band but you can t stretch a figure eight into a circle without tearing it. It is sometimes called rubber sheet geometry because the objects can be stretched and contracted like rubber but cannot be broken. An entry level primer on rubber sheet geometry.

Rubber sheet geometry topology does not distinguish between a circle and a square but it does between a circle and a figure eight. In a topology of two dimensions there is no difference between a circle and a square. Topology is sometimes called rubber sheet geometry. Topology or rubber sheet geometry topology is a branch of mathematics that deals with the ways in which figures can be distorted by stretching shrinking twisting or bending without changing certain basic properties.

A möbius strip a surface with only one side and one edge. For example a square can be deformed into a circle without breaking it but a figure 8 cannot. Math 560 introduction to topology what is topology. We can imagine the.

Topology studies properties of spaces that are invariant under any continuous deformation. Topology has been called rubber sheet geometry. Such shapes are an object of study in topology. Topology is the branch of mathematics that deals with surfaces and more general spaces and their properties such as compactness or connectedness that are preserved by continuous functions concepts such as neighborhood compactness connectedness and continuity all involve some notion of closeness of points to sets.
