On sensitivity in bipartite Cayley graphs [PDF]

open access: yes, 2020
Huang proved that every set of more than half the vertices of the $d$-dimensional hypercube $Q_d$ induces a subgraph of maximum degree at least $\sqrt{d}$, which is tight by a result of Chung, Füredi, Graham, and Seymour.

The Class of Non-Desarguesian Projective Planes is Borel Complete [PDF]

open access: yes, 2018
For every infinite graph $\Gamma$ we construct a non-Desarguesian projective plane $P^*_{\Gamma}$ of the same size as $\Gamma$ such that $Aut(\Gamma) \cong Aut(P^*_{\Gamma})$ and $\Gamma_1 \cong \Gamma_2$ iff $P^*_{\Gamma_1} \cong P^*_{\Gamma_2 ...

Poisson spaces with a transition probability [PDF]

open access: yes, 1996
The common structure of the space of pure states $P$ of a classical or a quantum mechanical system is that of a Poisson space with a transition probability.

Sperner property and finite-dimensional Gorenstein algebras associated to matroids [PDF]

open access: yes, 2016
We prove the Lefschetz property for a certain class of finite-dimensional Gorenstein algebras associated to matroids. Our result implies the Sperner property of the vector space lattice.

Beyond abstract elementary classes : On the model theory of geometric lattices [PDF]

open access: yes, 2018
Based on Crapo’s theory of one point extensions of combinatorial geometries, we find various classes of geometric lattices that behave very well from the point of view of stability theory.

Highest weight modules and polarized embeddings of shadow spaces [PDF]

open access: yes, 2010
Let Gamma be the K-shadow space of a spherical building Delta. An embedding V of Gamma is called polarized if it affords all "singular" hyperplanes of Gamma. Suppose that Delta is associated to a Chevalley group G. Then Gamma can be embedded into what we

Desargues maps and the Hirota-Miwa equation [PDF]

open access: yes, 2009
We study the Desargues maps $\phi:\ZZ^N\to\PP^M$, which generate lattices whose points are collinear with all their nearest (in positive directions) neighbours.

Decomposition and Structure theorems for Garside-like groups with modular lattice structure

open access: yes, 2023
Despite being a vast generalization of Garside groups, right $\ell$-groups with noetherian lattice structure and strong order unit share a lot of the properties of Garside groups.

Algebarsko modeliranje kvantno-mehaničkih jednadžbi u konačno i beskonačno dimenzionalnim Hilbertovim prostorima [PDF]

open access: yes, 2011
The Hilbert space of quantum mechanics has a dual representation in lattice theory, called the Hilbert lattice. In addition to offering the potential for new insights, the lattice-theoretical approach may be computationally efficient for certain kinds of

Foundations of matroids -- Part 2: Further theory, examples, and computational methods

open access: yes, 2023
In this sequel to "Foundations of matroids - Part 1", we establish several presentations of the foundation of a matroid in terms of small building blocks.
