Cycle-continuous mappings -- order structure
Robert Šámal
Given two graphs, a mapping between their edge-sets is cycle-continuous, if the preimage of every cycle is a cycle. The motivation for this notion is Jaeger's conjecture that for e…
Non-embeddability of geometric lattices and buildings
Martin Tancer, Kathrin Vorwerk
A fundamental question for simplicial complexes is to find the lowest dimensional Euclidean space in which they can be embedded. We investigate this question for order complexes of…
Mutually unbiased bases as submodules and subspaces
Joanne L. Hall, Jan Stovicek
Mutually unbiased bases (MUBs) have been used in several cryptographic and communications applications. There has been much speculation regarding connections between MUBs and finit…
Planar Difference Functions
Joanne L. Hall, Asha Rao, Diane Donovan
In 1980 Alltop produced a family of cubic phase sequences that nearly meet the Welch bound for maximum non-peak correlation magnitude. This family of sequences were shown by Wooter…
Quasirandom permutations are characterized by 4-point densities
Daniel Král', Oleg Pikhurko
For permutations P and T of lengths |P|\le|T|, let t(P,T) be the probability that the restriction of T to a random |P|-point set is (order) isomorphic to P. We show that every sequ…
Homomorphism-homogeneous L-colored graphs
David Hartman, Jan Hubicka, Dragan Masulovic
A relational structure is homomorphism-homogeneous (HH-homogeneous for short) if every homomorphism between finite induced substructures of the structure can be extended to a homom…
