A continuous analogue of Erdős' -Sperner theorem

Themis Mitsis, Christos Pelekis, Václav Vlasák

A \emph{chain} in the unit -cube is a set such that for every and in we either have $x_i\le y_…

A Turán-type theorem for large-distance graphs in Euclidean spaces, and related isodiametric problems

Martin Doležal, Jan Hladký, Jan Kolář +3

Given a measurable set we consider the "large-distance graph" , on the ground set , in which each pair of points from whose distance is…

Projection inequalities for antichains

Konrad Engel, Themis Mitsis, Christos Pelekis +1

A set is called an antichain (resp. antichain) if it does not contain two distinct elements and ${\mathbf y}=(y_1,\ldot…

The de Bruijn-Erdős theorem from a Hausdorff measure point of view

Martin Doležal, Themis Mitsis, Christos Pelekis

Motivated by a well-known result in extremal set theory, due to Nicolaas Govert de Bruijn and Paul Erdős, we consider curves in the unit -cube of the form \[ A=\{(x,f_…

A fractal perspective on optimal antichains and intersecting subsets of the unit -cube

Konrad Engel, Themis Mitsis, Christos Pelekis

An \emph{-cube antichain} is a subset of the unit -cube that does not contain two elements and $\mathbf{y}=(y_1, y_2,\ldots, y_n…

Carleman estimates with convex power weights

Themis Mitsis

We prove Carleman estimates with convex power weights , extending previous work by J. O. Strömberg.

Menshov' "adjustment theorem" with respect to general measures

Themis Mitsis

A classical theorem of Menshov states that every measurable function can redefined on a set of arbitrarily small Lebesgue measure, so that the resulting function has uniformly conv…

The essential norm of a composition operator on the minimal Mobius invariant space

Themis Mitsis, Michael Papadimitrakis

We derive a formula for the essential norm of a composition operator on the minimal Mobius invariant space of analytic functions. As an application, we show that the essential norm…
