Almost tight upper bounds for vertical decompositions in four dimensions.

We show that the complexity of the vertical decomposition of an arrangement of n fixed-degree algebraic surfaces or surface patches in four dimensions is O(n4+ϵ), for any ϵ > 0. This improves the best previously known upper bound for this problem by a near-linear factor, and s...
