• Ultrametric space — In mathematics, an ultrametric space is a special kind of metric space in which the triangle inequality is replaced with d(x, z) ≤ max{d(x, y), d(y, z)}. Sometimes the associated metric is also called a non Archimedean metric or super metric.… …   Wikipedia

• Barrow's inequality — In geometry, Barrow s inequality states the following: Let P be a point inside the triangle ABC , U , V , and W be the points where the angle bisectors of BPC , CPA , and APB intersect the sides BC , CA , AB , respectively. Then: PA+PB+PCgeq… …   Wikipedia

• Metric (mathematics) — In mathematics, a metric or distance function is a function which defines a distance between elements of a set. A set with a metric is called a metric space. A metric induces a topology on a set but not all topologies can be generated by a metric …   Wikipedia

• Absolute value — For the philosophical term, see Value (ethics). For the Akrobatik album, see Absolute Value (album). In mathematics, the absolute value (or modulus) |a| of a real number a is the numerical value of a without regard to its sign. So, for example,… …   Wikipedia
