Abstract. We consider the asymptotic behavior, both in distribution and almost sure, of the Bahadur-Kiefer representation of the two dimensional spatial medians. The rates appearing in this expansion are non-standard. The rate in the almost sure expansion is n(2 log n)-1/2(2 log log n)-1. The set of clusters points in the almost sure representation is obtained. The distribution of the Bahadur-Kiefer representation of the two dimensional spatial medians converges with rate n(2 log n)-1/2 to a limit that is determined precisely.
Key words and phrases: Bahadur-Kiefer representations, spatial medians, empirical processes.
