Abstract We show that the complexity of the vertical decomposition of an arrangement of $\textit{n}$ fixed-degree algebraic surfaces or surface patches in four dimensions is $O(n^{4+ϵ}),$ for any ϵ > 0. This improves the best previously known upper bound for this problem by a near-linear factor, and settles a major problem in the theory of arrangements of surfaces, open since 1989. The new bound can be extended to higher dimensions, yielding the bound $O(n^{2d™4+ϵ}),$ for any ϵ > 0, on the complexity of vertical decompositions in dimensions $\textit{d}$ ≥ 4. We also describe the immediate algorithmic applications of these results, which include improved algorithms for point location, range searching, ray shooting, robot motion planning, and some geometric optimization problems.
