Axiomatic Characterization of the Mean Function on Trees

McMorris, F.R.; Mulder, H.M.; Ortega, O. - Erasmus University Rotterdam, Econometric Institute - 2010

A mean of a sequence Ï€ = (x1, x2, . . . , xk) of elements of a finite metric space (X, d) is an element x for which is minimum. The function Mean whose domain is the set of all finite sequences on X and is defined by Mean(Ï€) = { x | x is a mean of Ï€ } is called the mean function on...

Location Theory : A Unified Approach

Nickel, Stefan (contributor); Puerto, Justo (contributor) - 2005

Although modern location theory is now more than 90 years old, the focus of researchers in this area has been mainly problem oriented. However, a common theory, which keeps the essential characteristics of classical location models, is still missing. This monograph addresses this issue. A...
