Pattern Recognition on Oriented Matroids: K*-Vectors and Reorientations
arXiv:1010.1836
Abstract
The components of K*-vectors associated to a simple oriented matroid M are the numbers of general or special tope committees for M. Using the principle of inclusion-exclusion, we determine how the reorientations of M on one-element subsets of its ground set affect K*-vectors.
