A continuous analogue of Erdős' $k$ -Sperner theorem

Themis Mitsis, Christos Pelekis, Václav Vlasák

A \emph{chain} in the unit $n$ -cube is a set $C \subset [0, 1]^{n}$ such that for every $x = (x_{1}, \dots, x_{n})$ and $y = (y_{1}, \dots, y_{n})$ in $C$ we either have $x_i\le y_…

$L^{p} - L^{q}$ Carleman estimates with convex power weights

Themis Mitsis

We prove $L^{p} - L^{q}$ Carleman estimates with convex power weights $∣ x ∣^{β}$ , extending previous work by J. O. Strömberg.

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…
