On De la Peña Type Inequalities for Point Processes

Naiqi Liu, Vladimir V. Ulyanov, Hanchao Wang

There has been a renewed interest in exponential concentration inequalities for stochastic processes in probability and statistics over the last three decades. De la Peña \cite{d}…

Two-sided inequalities for the density function's maximum of weighted sum of chi-square variables

Sergey G. Bobkov, Alexey A. Naumov, Vladimir V. Ulyanov

Two--sided bounds are constructed for a probability density function of a weighted sum of chi-square variables. Both cases of central and non-central chi-square variables are consi…

Second Order Expansions for Sample Median with Random Sample Size

Gerd Christoph, Vladimir V. Ulyanov, Vladimir E. Bening

In practice, we often encounter situations where a sample size is not defined in advance and can be a random value. The randomness of the sample size crucially changes the asymptot…

Bootstrap confidence sets for spectral projectors of sample covariance

Alexey Naumov, Vladimir Spokoiny, Vladimir Ulyanov

Let be i.i.d. sample in with zero mean and the covariance matrix . The problem of recovering the projector onto an eigenspace of $\m…

Spin systems, spin coherent states and quasi-exactly solvable models

V. V. Ulyanov, O. B. Zaslavskii

Spin coherent states play a crucial role in defining QESM (quasi-exactly solvable models) establishing a strict correspondence between energy spectra of spin systems and low-lying…
