Graph of ultrametric type matrices
Did you know?
WebA distinguished subclass of inverse M-matrices is ultrametric matrices, which are important in applications such as taxonomy. Ultrametricity is revealed to be a relevant concept in linear algebra and discrete potential theory because of its relation with trees in graph theory and mean expected value matrices in probability theory. The discrete metric is an ultrametric.The p-adic numbers form a complete ultrametric space.Consider the set of words of arbitrary length (finite or infinite), Σ , over some alphabet Σ. Define the distance between two different words to be 2 , where n is the first place at which the words differ. The resulting metric is an … See more In mathematics, an ultrametric space is a metric space in which the triangle inequality is strengthened to $${\displaystyle d(x,z)\leq \max \left\{d(x,y),d(y,z)\right\}}$$. Sometimes the associated metric is also called a non … See more An ultrametric on a set M is a real-valued function (where ℝ denote the See more • A contraction mapping may then be thought of as a way of approximating the final result of a computation (which can be guaranteed to exist … See more • Kaplansky, I.
