Abstract

When (X, d) is a finite metric space and π = (x₁, ..., x_k) ∈ X^k, a central element for π is an element x of X for which max{d(x, x_i): i = 1, ..., k} is minimum. The function that returns the set of all central elements for any tuple π is called the center function on X. In this article, the center function on finite trees is characterized.
