Kochen-Specker sets and Hadamard matrices

Petr Lisonek

We introduce a new class of complex Hadamard matrices which have not been studied previously. We use these matrices to construct a new infinite family of parity proofs of the Koche…

Bijections for Weyl Chamber walks ending on an axis, using arc diagrams and Schnyder woods

Julien Courtiel, Éric Fusy, Mathias Lepoutre +1

In the study of lattice walks there are several examples of enumerative equivalences which amount to a trade-off between domain and endpoint constraints. We present a family of suc…

Lower Bounds on Words Separation: Are There Short Identities in Transformation Semigroups?

Andrei A. Bulatov, Olga Karpova, Arseny M. Shur +1

The words separation problem, originally formulated by Goralcik and Koubek (1986), is stated as follows. Let be the minimum number such that for any two words of length $\…

Weighted Lattice Walks and Universality Classes

Julien Courtiel, Stephen Melczer, Marni Mishna +1

In this work we consider two different aspects of weighted walks in cones. To begin we examine a particular weighted model, known as the Gouyou-Beauchamps model. Using the theory o…

Spectral radius and fractional matchings in graphs

Suil O

A {\it fractional matching} of a graph is a function giving each edge a number in so that for each , where is the s…

Interlacing families and the Hermitian spectral norm of digraphs

Gary Greaves, Bojan Mohar, O Suil

It is proved that for any finite connected graph , there exists an orientation of such that the spectral radius of the corresponding Hermitian adjacency matrix is smaller or…
