On the discrepancy of random subsequences of
Istvan Berkes, Bence Borda
For irrational , is uniformly distributed mod 1 in the Weyl sense, and the asymptotic behavior of its discrepancy is completely known. In contrast, very few precise res…
Sticky matroids and convolution
Laszlo Csirmaz
Motivated by the characterization of the lattice of cyclic flats of a matroid, the convolution of a ranked lattice and a discrete measure is defined, generalizing polymatroid convo…
Remarks on the distribution of colors in Gallai colorings
Joseph Feffer, Yaoying Fu, Jun Yan
A Gallai coloring of a complete graph is an edge coloring without triangles colored with three different colors. A sequence of positive integers is an…
The domination number of the graph defined by two levels of the -cube, II
József Balogh, Gyula O. H. Katona, William Linz +1
Consider all -element subsets and -element subsets of an -element set as vertices of a bipartite graph. Two vertices are adjacent if the corresponding $\ell…
On the generalized Fitting height and insoluble length of finite groups
Robert M. Guralnick, Gareth Tracey
We prove two conjectures of E. Khukhro and P. Shumyatsky concerning the Fitting height and insoluble length of finite groups. As a by-product of our methods, we also prove a genera…
On polyhedra inscribed in , with approximately equal edges
E. Makai
We consider triangle faced convex polyhedra inscribed in the unit sphere in . One way of measuring their deviation from regular polyhedra with triangular faces i…
Approximation of the average of some random matrices
Grigory Ivanov, Márton Naszódi, Alexandr Polyanskii
Rudelson's theorem states that if for a set of unit vectors and positive weights , we have that is the identity operator on …
Split-and-Merge in Stationary Random Stirring on Lattice Torus
Dmitry Ioffe, Bálint Tóth
We show that in any dimension , the cycle-length process of stationary random stirring (or, random interchange) on the lattice torus converges to the canonical Markovian spl…
Half-graphs, other non-stable degree sequences, and the switch Markov chain
Péter L. Erdős, Ervin Győri, Tamás Róbert Mezei +2
One of the simplest methods of generating a random graph with a given degree sequence is provided by the Monte Carlo Markov Chain method using switches. The switch Markov chain con…
Complexity of universal access structures
Laszlo Csirmaz
An important parameter in a secret sharing scheme is the number of minimal qualified sets. Given this number, the universal access structure is the richest possible structure, name…
On -close Sperner systems
Daniel Nagy, Balazs Patkos
For a set of positive integers, a set system is said to be -close Sperner, if for any pair of distinct sets in the skew d…
A Cantor-Bernstein-type theorem for spanning trees in infinite graphs
Joshua Erde, Pascal Gollin, Atilla Joó +2
We show that if a graph admits a packing and a covering both consisting of many spanning trees, where is some infinite cardinal, then the graph also admits a decomposition…
Lee-Yang Zeros of the antiferromagnetic Ising Model
Ferenc Bencs, Pjotr Buys, Lorenzo Guerini +1
We investigate the location of zeros for the partition function of the anti-ferromagnetic Ising Model, focusing on the zeros lying on the unit circle. We give a precise characteriz…
Between the deterministic and non-deterministic query complexity
Dániel Gerbner
We consider problems that can be solved by asking certain queries. The deterministic query complexity of a problem is the smallest number of queries needed to ask in o…
On the best constants associated with -distances
Gergely Kiss, Jean-Luc Marichal
We pursue the investigation of the concept of -distance, an -variable version of the classical concept of distance recently introduced and investigated by Kiss, Marichal, and…
Counting bounded elements of a number field
Mikołaj Frączyk, Gergely Harcos, Péter Maga
We estimate, in a number field, the number of elements and the maximal number of linearly independent elements, with prescribed bounds on their valuations. As a by-product, we obta…
Edge-ordered Ramsey numbers
Martin Balko, Máté Vizer
We introduce and study a variant of Ramsey numbers for edge-ordered graphs, that is, graphs with linearly ordered sets of edges. The edge-ordered Ramsey number $\overline{R}_e(\mat…
-inverse monoids as algebraic structures in enriched signature
K. Auinger, G. Kudryavtseva, M. B. Szendrei
Every -inverse monoid can be equipped with the unary operation which maps each element to the maximum element of its -class. In this enriched signature, the class of all -…
Inequalities for doubly nonnegative functions
Alexander Sidorenko
Let be a bounded symmetric measurable nonnegative function on , and . For a graph with vertices $\{v_1,v_…
The Fuglede conjecture for convex domains is true in all dimensions
Nir Lev, Máté Matolcsi
A set is said to be spectral if the space has an orthogonal basis of exponential functions. A conjecture due to Fuglede (1974) stated that is a…
Risk-neutral pricing for APT
Laurence Carassus, Miklos Rasonyi
We consider infinite dimensional optimization problems motivated by the financial model called Arbitrage Pricing Theory. Using probabilistic and functional analytic tools, we provi…
Polarization, sign sequences and isotropic vector systems
Gergely Ambrus, Sloan Nietert
We determine the order of magnitude of the th -polarization constant of the unit sphere for every and . For , we prove that extremizers…
New bounds on even cycle creating Hamiltonian paths using expander graphs
Gergely Harcos, Daniel Soltész
We say that two graphs on the same vertex set are -creating if their union (the union of their edges) contains as a subgraph. Let be the maximum number of pairwise…
The mixing time of the switch Markov chains: a unified approach
Péter L. Erdős, Catherine Greenhill, Tamás Róbert Mezei +3
Since 1997 a considerable effort has been spent to study the mixing time of switch Markov chains on the realizations of graphic degree sequences of simple graphs. Several results w…
