Confidence regions for the multidimensional density in the uniform norm based on the recursive Wolverton-Wagner estimation

Maria Rosaria Formica, Eugeny Ostrovsky, Leonid Sirota

We construct an optimal exponential tail decreasing confidence region for an unknown density of distribution in the Lebesgue-Riesz as well as in the uniform} norm, built on the sam…

Moment and exponential estimation for the distribution of the norms for random matrices martingales

Maria Rosaria Formica, Eugeny Ostrovsky, Leonid Sirota

We derive sharp non - asymptotical Lebesgue - Riesz as well as Grand Lebesgue Space norm estimations for different norms of matrix martingales through these norms for the correspon…

Homogeneous kernel integral operators in Grand Lebesgue Spaces

Maria Rosaria Formica, Eugeny Ostrovsky, Leonid Sirota

In this short report we estimate and calculate the exact value of norms of multilinear integral operators having homogeneous kernel, acting between two Grand Lebesgue Spaces.

Factorizable convergence of random variables in Grand Lebesgue Spaces

Maria Rosaria Formica, Eugeny Ostrovsky, Leonid Sirota

We obtain results concerning the so-called factorization for the convergence of random variables almost everywhere (almost surely or with probability one), belonging to the classic…

Norm estimates in Grand Lebesgue Spaces for some operators, including magic square matrices

Maria Rosaria Formica, Eugeny Ostrovsky, Leonid Sirota

We extend the classical Lebesgue-Riesz norm estimations for integral operators acting between different classical Lebesgue-Riesz spaces into the Grand Lebesgue Spaces, in the gener…

Relations between Lorentz-Zygmund and Grand Lebesgue Spaces and norms

Maria Rosaria Formica, Eugeny Ostrovsky, Leonid Sirota

We establish imbedding properties between Grand Lebesgue Spaces and (generalized) Lorentz-Zygmund ones. We extend some known previous results concerning imbedding theorems between…
