Abstract

A \textit{kk-transversal} to family of sets in Rd\mathbb{R}^d is a kk-dimensional affine subspace that intersects each set of the family. In 1957 Hadwiger provided a necessary and sufficient condition for a family of pairwise disjoint, planar convex sets to have a 11-transversal. After a series of three papers among the authors Goodman, Pollack, and Wenger from 1988 to 1990, Hadwiger's Theorem was extended to necessary and sufficient conditions for (d1)(d-1)-transversals to finite families of convex sets in Rd\mathbb{R}^d with no disjointness condition on the family of sets. We prove an analogue of the Goodman-Pollack-Wenger theorem in the complex setting.

Correction: A complex Goodman-Pollack-Wenger theorem is proven as in the main theorem of the first version. It does not imply a corresponding result for real transversals as initially stated
