INITIAL L2 x middot middot middot x L2 BOUNDS FOR MULTILINEAR OPERATORS
The Lp boundedness theory of convolution operators is based on an initial L2-+ L2 estimate derived from the Fourier transform. The corresponding theory of multilinear operators lacks such a simple initial estimate ...

Estimates of the principal eigenvalue of the p-biharmonic operator
We provide estimates from below and from above for the principal eigenvalue of the p-biharmonic operator on a bounded domain with the Navier boundary conditions. We apply these estimates to study the asymptotic behavior of ...

Estimates for imaginary powers of the Laplace operator in variable Lebesgue spaces and applications
In this paper we study some estimates of norms in variable exponent Lebesgue spaces for singular integral operators that are imaginary powers of the Laplace operator in $R^n$. Using the Mellin transform argument, from these...

Estimates of the Principal Eigenvalue of the p-Laplacian and the p-Biharmonic Operator
We survey recent results concerning estimates of the principal eigenvalue of the Dirichlet p-Laplacian and the Navier p-biharmonic operator on a ball of radius $R$ in $R^N$ and its asymptotics for p approaching 1 and infinity....

Maximum-likelihood estimation of statistical operators of few-photon states
We deal with the estimation of the state of a d-level system, d }= 2, the so-called qudit, using a somewhat formal generalization of the measurement of the Pauli operators. The optical qubits, qutrits and qudits, in general, are sup...

Statistical methods for reliability evaluation based on operational data.
The paper deals with non-parametric estimators of the reliability function (especialy with the Kaplan-Meier and Nelson-Altschuler estimators) based on operational data (censored data, truncated data, repairable systems)....

Power system state estimator based on synchronous phasor measurement
provide synchronously measured voltage and current phasors. Commonly used estimators this qualitatively better measurements can not provide. That is why a new estimator was suggested. Designed estimator is composed of ...
