Abstract: We consider the problem of bounding the complexity of the kth level in an arrangement of n curves or surfaces, a problem dual to, and an extension of, the wellknown kset problem. Among other results, we prove a new bound, O(nk5/3), on the complexity of the kth level in an arrangement of n planes in ℝ3, or on the number of ksets in a set of n points in three dimensions, and we show that the complexity of the kth level in an arrangement of n line segments in the plane is O(n√kα(n/k)), and that the complexity of the kth level in an arrangement of n triangles in 3space is O(n2k5/6α(n/k)).
