When ( X, d ) is a finite metric space and π = ( x 1 , …, 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. © John Wiley & Sons, Inc.
