# Computational geometry and topology

• ## Are geometry and topology related?

Geometry deals with quantitative properties of space, such as distance and curvature on manifolds.
Topology deals with more qualitative properties of space, namely those that remain unchanged under bending and stretching. (For this reason, topology is often called “the geometry of rubber sheets”.).

• ## How is topology related to geometry?

Topology studies properties of spaces that are invariant under any continuous deformation.
It is sometimes called "rubber-sheet geometry" because the objects can be stretched and contracted like rubber, but cannot be broken.
For example, a square can be deformed into a circle without breaking it, but a figure 8 cannot..

• ## How is topology used in computer science?

Network topologies describe the arrangement of networks and the relative location of traffic flows.
Administrators can use network topology diagrams to determine the best placements for each node and the optimal path for traffic flow..

• ## Is topology part of geometry?

Topology is almost the most basic form of geometry there is.
It is used in nearly all branches of mathematics in one form or another..

• ## What is a computational topology?

Algorithmic topology, or computational topology, is a subfield of topology with an overlap with areas of computer science, in particular, computational geometry and computational complexity theory..

• ## What is computational topology used for?

A primary concern of algorithmic topology, as its name suggests, is to develop efficient algorithms for solving problems that arise naturally in fields such as computational geometry, graphics, robotics, structural biology and chemistry, using methods from computable topology..

• ## What is the relationship between geometry and topology?

Topology deals with more qualitative properties of space, namely those that remain unchanged under bending and stretching. (For this reason, topology is often called “the geometry of rubber sheets”.).

• ## What is topology and geometry?

Distinction between geometry and topology
The study of metric spaces is geometry, the study of topological spaces is topology.
The terms are not used completely consistently: symplectic manifolds are a boundary case, and coarse geometry is global, not local..

• The emerging field of computational topology utilizes theory from topology and the power of computing to solving problems in diverse fields.
Recent applications include computer graphics, computer-aided design (CAD), and structural biology.
• There are many fields of computer science that deal with computational geometry problems.
These include computer vision, graphics, robotics, image processing and computer-aided design and manufacturing.
• Topology is used in many branches of mathematics, such as differentiable equations, dynamical systems, knot theory, and Riemann surfaces in complex analysis.
It is also used in string theory in physics, and for describing the space-time structure of universe.

Branch of topology

In mathematics, low-dimensional topology is the branch of topology that studies manifolds, or more generally topological spaces, of four or fewer dimensions.
Representative topics are the structure theory of 3-manifolds and 4-manifolds, knot theory, and braid groups.
This can be regarded as a part of geometric topology.
It may also be used to refer to the study of topological spaces of dimension 1, though this is more typically considered part of continuum theory.
