Abstract

A dynamic data structure is given that maintains the minimal distance in a set ofn points ink-dimensional space inO((logn)k log logn) amortized time per update. The size of the data structure is bounded byO(n(logn)k). Distances are measured in the MinkowskiLt-metric, where 1 ≤t ≤ ?. This is the first dynamic data structure that maintains the minimal distance in polylogarithmic time for fully on-line updates.
