Dudley-type bound for stationary Bernoulli processes

W. Bednorz, R. Martynek, R. Meller

This is preliminary, AI-generated note on the Dudley-type bound for stationary Bernoulli processes postulated by M. Talagrand based on the unpublished notes of the authors and the…

Moment estimates for chaoses with regular moment growth

Rafał Meller

We give two-sided moment estimates for decoupled chaoses of any order generated by independent symmetric random variables with regular moment growth: for e…

Sudakov Minoration for Unconditional Log-Concave Vectors

Witold Bednorz, Rafal Martynek, Rafal Meller

Sudakov minoration asks whether a large family of separated random linear forms must have a large expected maximum. We present a proof candidate for this principle for all uncondit…

Sudakov minoration for unconditional log-concave vectors with negatively associated magnitudes

Witold Bednorz, Rafal Martynek, Rafal Meller

We prove the Sudakov minoration principle, with a universal constant, for unconditional log-concave random vectors whose coordinate magnitudes are negatively associated. The main s…

Operator-norm Sudakov minoration for Gaussian chaos of order two

Witold Bednorz, Rafał Martynek, Rafał Meller

We prove that an operator-norm separated family of matrices satisfies , where G,G' are independent standard Gaussian vectors and a…

A Gaussian Chain Rule Proof of the Banach Space Hanson Wright Bound

Witold Bednorz, Rafal Martynek, Rafal Meller

For a finite family of real matrices, we bound the Gaussian width of the union of its image ellipsoids by its maximal Hilbert Schmidt norm, its maximal fixed input Gaussian width,…

A candidate proof of the sharp Latala and Strzelecka Gaussian matrix bound

Witold Bednorz, Rafal Martynek, Rafal Meller

We give a candidate proof of Conjecture 5 in the third arXiv version of Latala and Strzelecka Operator lp lq norms of Gaussian matrices.

A short proof of the Bernoulli decomposition theorem

Witold Bednorz Rafal Martynek, Rafal Meller

We give a construction of admissible partitions that yields the Bernoulli decomposition theorem

An invariant variational proof for canonical processes with independent symmetric log-concave tails

Witold Bednorz, Rafal Martynek, Rafal Meller

We prove a prescribed-index-law comparison for canonical processes with independent symmetric coordinates having log-concave tails, with no doubling assumption

Sudakov minoration for weighted Orlicz balls

Witold Bednorz, Witold Bednorz Rafal Martynek, Rafal Meller +1

We give a proof of a universal Sudakov minoration principle for measures based on wighted Orlicz balls.

Spectral norm of matrices with independent entries up to polyloglog

Rafał Meller

In this paper, we study the expectation of the operator norm of the random matrix (a_{ij} X_{ij}) for i,j <= n, under the assumption that the random variables (X_{ij}) are independ…

Small cover approach to the suprema of positive canonical processes

Witold Bednorz, Rafał Martynek, Rafał Meller

We extend the recent result of Park and Pham concerning the positive selector process to canonical processes generated by i.i.d. nonnegative random variables satisfying minimal tai…

The suprema of selector processes with the application to positive infinitely divisible processes

Witold Bednorz, Rafał Martynek, Rafał Meller

We provide an alternative proof of the recent result by Park and Pham (2022) on the expected suprema of positive selector and empirical processes. We extend it to positive infinite…
