The odd-even invariant and Hamiltonian circuits in tope graphs
Yvonne Kemper, Jim Lawrence
In this paper we consider the question of the existence of Hamiltonian circuits in the tope graphs of central arrangements of hyperplanes. Some of the results describe connections…
Approximating the Chromatic Polynomial
Yvonne Kemper, Isabel Beichl
Chromatic polynomials are important objects in graph theory and statistical physics, but as a result of computational difficulties, their study is limited to graphs that are small,…
Flows on Simplicial Complexes
Matthias Beck, Yvonne Kemper
Given a graph , the number of nowhere-zero $\ZZ_q$-flows is known to be a polynomial in . We extend the definition of nowhere-zero $\ZZ_q$-flows to simplicial comple…
-vectors of small matroid complexes
Jesus DeLoera, Yvonne Kemper, Steven Klee
Stanley conjectured in 1977 that the -vector of a matroid simplicial complex is a pure -sequence. We give simple constructive proofs that the conjecture is true for matroids…
