• Glossary of topology — This is a glossary of some terms used in the branch of mathematics known as topology. Although there is no absolute distinction between different areas of topology, the focus here is on general topology. The following definitions are also… …   Wikipedia

• Compact-open topology — In mathematics, the compact open topology is a topology defined on the set of continuous maps between two topological spaces. The compact open topology is one of the commonly used topologies on function spaces, and is applied in homotopy theory… …   Wikipedia

• Path (topology) — The points traced by a path from A to B in R². However, different paths can trace the same set of points. In mathematics, a path in a topological space X is a continuous map f from the unit interval I = [0,1] to X f : I → X. The initial… …   Wikipedia

• Loop (topology) — In mathematics, a loop in a topological space X is a path f from the unit interval I = [0,1] to X such that f (0) = f (1). In other words, it is a path whose initial point is equal to the terminal point.A loop may also be seen as a continuous map …   Wikipedia

• Magnesium transporter — This page links directly from the magnesium in biological systems page. Magnesium transporters are proteins that transport magnesium across the cell membrane. All forms of life require magnesium, yet the molecular mechanisms of Mg2+ uptake from… …   Wikipedia

• Pseudometric space — In mathematics, a pseudometric space is a generalized metric space in which the distance between two distinct points can be zero. In the same way as every normed space is a metric space, every seminormed space is a pseudometric space. Because of… …   Wikipedia

• CW complex — In topology, a CW complex is a type of topological space introduced by J. H. C. Whitehead to meet the needs of homotopy theory. This class of spaces is broader and has some better categorical properties than simplicial complexes, but still… …   Wikipedia
