What is mean by topology in maths?
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.
What is called topology?
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.
Why is it called topology?
In mathematics, topology (from the Greek words τόπος, ‘place, location’, and λόγος, ‘study’) is concerned with the properties of a geometric object that are preserved under continuous deformations, such as stretching, twisting, crumpling, and bending; that is, without closing holes, opening holes, tearing, gluing, or …
Is topology used in physics?
Topology is implicitly applied in almost all of physics. The reason is, it is a prerequisite for most of the mathematics that is used in physics. For instance, quantum mechanics uses a Hilbert space , which requires topology for a rigorous formulation.
Who is the father of topology?
His most famous example was a non-orientable surface, which is now called the Möbius strip. The Russian born mathematician Georg Ferdinand Ludwig Philipp Cantor, the father of set theory, is another mathematician to whom we owe credit for topology….Topology/History.

What is the difference between topology and geometry?
Distinction between geometry and topology. Geometry has local structure (or infinitesimal), while topology only has global structure. Alternatively, geometry has continuous moduli, while topology has discrete moduli. By examples, an example of geometry is Riemannian geometry, while an example of topology is homotopy theory.
What is math topology used for in real life?
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 .
What are the different types of topology?
There are two main types of topology. Network topologies may be physical or logical. Physical topology means the physical design of a network including the devices, locations and cables. Logical topology is about how data is actually moved around in a network, not its physical design.
How many types of topology?
There are seven basic types of network topologies in the study of network topology: Point-to-point topology, bus (point-to-multipoint) topology, ring topology, star topology, hybrid topology, mesh topology and tree topology.
