An ultrametric space is a special kind of metric space in which the triangle inequality is replaced with the stronger condition d (x,z)\le \max \left\ { d (x,y),d (y,z)\right\} .

Here ν p ( a) is the largest number of powers of p dividing a (possibly negative, or ∞ for a = 0 ). So things are small exactly when they are highly divisible by p. This makes Q into an example of an ultrametric space, because the number of powers of p ...
WebJan 1, 2014 · This chapter is devoted to the study of ultrametric matrices introduced by Martínez, Michon and San Martín in [44], where it was proved that the inverse of an ultrametric matrix is a row diagonally dominant Stieltjes matrix (a particular case of an M-matrix).We shall include this result in Theorem 3.5 and give a proof in the lines done by … WebApr 6, 2024 · This is an old question, but all of the previous answers require the tree to be made ultrametric before being converted to a dendrogram object.

WebThe ultrametricity of the tree is a direct consequence of the non-intersecting property of the locally optimal paths. In ultrametric space, any three points A1, A2 and A3 satisfy the inequality [22]: (19) where U ( Ai, Aj) denotes the ultrametric distance between the points Ai and Aj. Now consider three sites A1, A2 and A3 on the base of the delta.
WebThe distance within an ultrametric is the same as the minimax path weight in the minimum spanning tree of the metric. From the minimum spanning tree, one can construct a Cartesian tree, the root node of which represents the heaviest edge of the minimum spanning tree. Removing this edge partitions the minimum spanning tree into two …
