General topology General topology is the branch of topology dealing with the basic set-theoretic definitions and constructions used in topology. Another name for general topology is point-set topology.

The fundamental concepts in point-set topology are continuity, compactness, and connectedness. Intuitively, continuous functions take nearby points to nearby points. Compact sets are those that can be covered by finitely many sets of arbitrarily small size.

Connected sets are sets that cannot be divided into two pieces that are far apart.

The words nearby, arbitrarily small, and far apart can all be made precise by using open sets. If we change the definition of open set, we change what continuous functions, compact sets, and connected sets are.

Each choice of definition for open set is called a topology. A set with a topology is called a topological space. Metric spaces are an important class of topological spaces where distances can be assigned a number called a metric. Having a metric simplifies many proofs, and many of the most common topological spaces are metric spaces.

Algebraic topology Algebraic topology is a branch of mathematics that uses tools from abstract algebra to study topological spaces. The most important of these invariants are homotopy groupshomology, and cohomology.

Although algebraic topology primarily uses algebra to study topological problems, using topology to solve algebraic problems is sometimes also possible. Algebraic topology, for example, allows for a convenient proof that any subgroup of a free group is again a free group.

Differential topology Differential topology is the field dealing with differentiable functions on differentiable manifolds. More specifically, differential topology considers the properties and structures that require only a smooth structure on a manifold to be defined.

Smooth manifolds are 'softer' than manifolds with extra geometric structures, which can act as obstructions to certain types of equivalences and deformations that exist in differential topology.

For instance, volume and Riemannian curvature are invariants that can distinguish different geometric structures on the same smooth manifold—that is, one can smoothly "flatten out" certain manifolds, but it might require distorting the space and affecting the curvature or volume.

Geometric topology Geometric topology is a branch of topology that primarily focuses on low-dimensional manifolds i. In high-dimensional topology, characteristic classes are a basic invariant, and surgery theory is a key theory.

Low-dimensional topology is strongly geometric, as reflected in the uniformization theorem in 2 dimensions — every surface admits a constant curvature metric; geometrically, it has one of 3 possible geometries: Generalizations[ edit ] Occasionally, one needs to use the tools of topology but a "set of points" is not available.

In pointless topology one considers instead the lattice of open sets as the basic notion of the theory, [19] while Grothendieck topologies are structures defined on arbitrary categories that allow the definition of sheaves on those categories, and with that the definition of general cohomology theories.

These enzymes cut, twist, and reconnect the DNA, causing knotting with observable effects such as slower electrophoresis.

In neuroscience, topological quantities like the Euler characteristic and Betti number have been used to measure the complexity of patterns of activity in neural networks. Computer science[ edit ] Topological data analysis uses techniques from algebraic topology to determine the large scale structure of a set for instance, determining if a cloud of points is spherical or toroidal.

The main method used by topological data analysis is: Replace a set of data points with a family of simplicial complexesindexed by a proximity parameter. Analyse these topological complexes via algebraic topology — specifically, via the theory of persistent homology. The topological dependence of mechanical properties in solids is of interest in disciplines of mechanical engineering and materials science.

Electrical and mechanical properties depend on the arrangement and network structures of molecules and elementary units in materials. A topological quantum field theory or topological field theory or TQFT is a quantum field theory that computes topological invariants.Therefore it has become so easy to draw network topology diagrams, network mapping, home network, wireless network diagram, Cisco network topologies, network cable diagrams, logical network diagrams, network wiring diagrams, LAN network diagrams, activity network diagrams, network topology diagrams, local network area diagrams, .

- LAN, MAN and WAN Network Topologies There are many different types of network topologies, but the three most common types are LANs, MANs, and WANs.

The LAN topology is probably the most common of the three. - Developing a Computer Network for Bead Bar Introduction This essay will outline my recommendations for the . Here's information about common computer network topologies like the bus, star, and ring for computer network design.
