Slicing $ℓ_{p}$ -balls reloaded: stability, planar sections in $ℓ_{1}$

Giorgos Chasapis, Piotr Nayar, Tomasz Tkocz

We show that the two-dimensional minimum-volume central section of the $n$ -dimensional cross-polytope is attained by the regular $2 n$ -gon. We establish stability-type results for h…

Rademacher-Gaussian tail comparison for complex coefficients and related problems

Giorgos Chasapis, Ruoyuan Liu, Tomasz Tkocz

We provide a generalisation of Pinelis' Rademacher-Gaussian tail comparison to complex coefficients. We also establish uniform bounds on the probability that the magnitude of weigh…

Sharp bounds on $p$ -norms for sums of independent uniform random variables, $0 < p < 1$

Giorgos Chasapis, Keerthana Gurushankar, Tomasz Tkocz

We provide a sharp lower bound on the $p$ -norm of a sum of independent uniform random variables in terms of its variance when $0 < p < 1$ . We address an analogous question for $p$ -…
