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…

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…

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.

New estimates for convex layer numbers

Gergely Ambrus, Peter Nielsen, Caledonia Wilson

Starting with a finite point set , the peeling process repeatedly removes the set of the vertices of the convex hull of the current set. The number of peeli…

Isometric study of Wasserstein spaces --- the real line

György Pál Gehér, Tamás Titkos, Dániel Virosztek

Recently Kloeckner described the structure of the isometry group of the quadratic Wasserstein space . It turned out that the case of the rea…

Uniform tight frames as optimal signals

Gergely Ambrus, Bo Bai, Jianfeng Hou

Non-orthogonal communication is a promising technique for future wireless networks (e.g., 6G and Wi-Fi 7). In the vector channel model, designing efficient non-orthogonal communica…

Strengthened inequalities for the mean width and the -norm

Károly J. Böröczky, Ferenc Fodor, Daniel Hug

Barthe proved that the regular simplex maximizes the mean width of convex bodies whose John ellipsoid (maximal volume ellipsoid contained in the body) is the Euclidean unit ball; o…
