D(x,y)≤ d(x,z)d(z,y) If x=y, then the left hand side is zero and the inequality certainly holds If x6= y, then the left hand side is equal to 1 Since x6= y, we must have either z6= xor else z6= y Thus, the right hand side is at least 1and the triangle inequality holds in any case.

Oct 14, 03 · Definition A partition of a set X is a set of nonempty subsets of X such that every element x in X is in exactly one of these subsets (ie, X is a disjoint union of the subsets) Equivalently, a family of sets P is a partition of X if and only if all of the following conditions hold The family P does not contain the empty set (that is );.
