Optimal offline virtual network embedding with rent-at-bulk aspects
Stefano Coniglio, Boris Grimm, Arie M. C. A. Koster +2
Network virtualization techniques allow for the coexistence of many virtual networks (VNs) jointly sharing the resources of an underlying substrate network. The Virtual Network Emb…
On Kalai's conjectures concerning centrally symmetric polytopes
Raman Sanyal, Axel Werner, Günter M. Ziegler
In 1989 Kalai stated the three conjectures A, B, C of increasing strength concerning face numbers of centrally symmetric convex polytopes. The weakest conjecture, A, became known a…
Unimodality and convexity of f-vectors of polytopes
Axel Werner
We consider unimodality and related properties of f-vectors of polytopes in various dimensions. By a result of Kalai (1988), f-vectors of 5-polytopes are unimodal. In higher dimens…
Constructions for 4-Polytopes and the Cone of Flag Vectors
Andreas Paffenholz, Axel Werner
We describe a construction for d-polytopes generalising the well known stacking operation. The construction is applied to produce 2-simplicial and 2-simple 4-polytopes with g_2=0 o…
