Large signed subset sums

Gergely Ambrus, Bernardo González Merino

We study the following question: for given , and , what is the largest value such that from any set of unit vectors in , w…

On non-adaptive majority problems of large query size

Dániel Gerbner, Máté Vizer

We are given balls and an unknown coloring of them with two colors. Our goal is to find a ball that belongs to the larger color class, or show that the color classes have the s…

Distribution of Beurling primes and zeroes of the Beurling zeta function I. Distribution of the zeroes of the zeta function of Beurling

Szilárd Gy. Révész

We prove three results on the density resp. local density and clustering of zeros of the Beurling zeta function close to the one-line . The analysis here brings…

Two-variable logic has weak, but not strong, Beth definability

H. Andréka, I. Németi

We prove that the two-variable fragment of first-order logic has the weak Beth definability property. This makes the two-variable fragment a natural logic separating the weak and t…

Fuglede's conjecture holds for cyclic groups of order

Gergely Kiss, Romanos Diogenes Malikiosis, Gábor Somlai +1

The tile-spectral direction of the discrete Fuglede-conjecture is well-known for cyclic groups of square-free order, initiated by Laba and Meyerowitz, but the spectral-tile directi…

Stochastic reaction-diffusion equations on networks

Mihály Kovács, Eszter Sikolya

We consider stochastic reaction-diffusion equations on a finite network represented by a finite graph. On each edge in the graph a multiplicative cylindrical Gaussian noise driven…

On the lack of semimartingale property

Vilmos Prokaj, László Bondici

In this work we extend the characterization of semimartingale functions in Cinlar et al. (1980) to the non-Markovian setting. We prove that if a function of a semimartingale remain…

On the discrepancy of random subsequences of II

Istvan Berkes, Bence Borda

Let be an irrational number, let be independent, identically distributed, integer-valued random variables, and put . Assuming that $X_1…

A note on thickness of knots

Andras I. Stipsicz, Zoltan Szabo

We introduce a numerical invariant β(K) of a knot K which measures how non-alternating K is. We prove an inequality between β(K) and the (knot Floer) thickness of K. As an applicat…

Non-orientable link cobordisms and torsion order in Floer homologies

Sherry Gong, Marco Marengon

We use unoriented versions of instanton and knot Floer homology to prove inequalities involving the Euler characteristic and the number of local maxima appearing in unorientable co…

Longest k-monotone chains

Gergely Ambrus

We study higher order convexity properties of random point sets in the unit square. Given uniform i.i.d random points, we derive asymptotic estimates for the maximal number of…

Singularity of maps of several variables and a problem of Mycielski concerning prevalent homeomorphisms

Richárd Balka, Márton Elekes, Viktor Kiss +1

S. Banach pointed out that the graph of the generic (in the sense of Baire category) element of has length . J. Mycielski asked if the measure theoretic du…

On Turán numbers of the complete -graphs

Alexander Sidorenko

The Turán number is the minimum number of edges in an -vertex -graph whose independence number does not exceed . For each , there exists suc…

Computing the covering radius of a polytope with an application to lonely runners

Jana Cslovjecsek, Romanos Diogenes Malikiosis, Márton Naszódi +1

We are concerned with the computational problem of determining the covering radius of a rational polytope. This parameter is defined as the minimal dilation factor that is needed f…

An improved quantum-inspired algorithm for linear regression

András Gilyén, Zhao Song, Ewin Tang

We give a classical algorithm for linear regression analogous to the quantum matrix inversion algorithm [Harrow, Hassidim, and Lloyd, Physical Review Letters'09, arXiv:0811.3171] f…

Flows on measurable spaces

Laszlo Lovasz

The theory of graph limits is only understood to any nontrivial degree in the cases of dense graphs and of bounded degree graphs. There is, however, a lot of interest in the interm…

On directed analogues of expander and hyperfinite graph sequences

Endre Csóka, Łukasz Grabowski

We introduce and study analogues of expander and hyperfinite graph sequences in the context of directed acyclic graphs, which we call "extender" and "hypershallow" graph sequences,…

Sumsets of Semiconvex sets

Imre Ruzsa, Jozsef Solymosi

We investigate additive properties of sets where is a monotone increasing set of real numbers, and the differences of consecutive elements are all…

The density hypothesis for horizontal families of lattices

Mikołaj Frączyk, Gergely Harcos, Péter Maga +1

We prove the density hypothesis for wide families of arithmetic orbifolds arising from all division quaternion algebras over all number fields of bounded degree. Our power-saving b…

Visualizing Transfer Learning

Róbert Szabó, Dániel Katona, Márton Csillag +2

We provide visualizations of individual neurons of a deep image recognition network during the temporal process of transfer learning. These visualizations qualitatively demonstrate…

The cocked hat

Imre Bárány, William Steiger, Sivan Toledo

We revisit the cocked hat -- an old problem from navigation -- and examine under what conditions its old solution is valid.

Weakly saturated random graphs

Zsolt Bartha, Brett Kolesnik

As introduced by Bollobás, a graph is weakly -saturated if the complete graph is obtained by iteratively completing copies of minus an edge. For all graphs , we…

Data-dependent Pruning to find the Winning Lottery Ticket

Dániel Lévai, Zsolt Zombori

The Lottery Ticket Hypothesis postulates that a freshly initialized neural network contains a small subnetwork that can be trained in isolation to achieve similar performance as th…
