Embracing exchange sequences and oriented matroid polyhedron diameter
Kristóf Bérczi, Kolja Knauer, Luis Pedro Montejano +1
We reduce the embracing exchange distance of bases of oriented matroids to the metric of oriented matroid polyhedra. This allows us to disprove recent conjectures of Caoduro, Khoda…

Luis Montejano, Edgardo Roldán-Pensado
In this paper we develop a concrete way to construct bodies of constant width in dimension three. They are constructed from special embeddings of self-dual graphs.
