Estimates of the principal eigenvalue of the p-Laplacian

We provide estimates from below and from above for the principal eigenvalue of the p-Laplacian on a bounded domain. We apply these estimates to study the asymptotic behavior of the principal eigenvalue for...

Zeros of derivatives of solutions to singular (p,n-p) conjugate BVPs

Positive solutions of the singular (p,n-p) conjugate BVP are studied. The set of all zeros of their derivatives up to order $n-1$ is described. By means of this, estimates from below of the solutions and the absolute values...

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 asymp...

A lower bound for the mixture parameter in the binary mixture model and its estimator

The paper discusses an approach to estimate the mixture parameter in the binary mixture model. An inequality which bounds the mixture parameter from below is obtained. The lower bound of the inequality is estimated...

Data-driven estimation of invisible energy below EeV

measured by optical telescopes below 1 EeV. Usually, estimations of the invisible energy below 1 EeV relied on Monte Carlo simulations despite the fact that modelsThe calorimetric energy of a cosmic-ray shower is measured ...

Spectral estimates for a class of Schrodinger operators with infinite phase space and potential unbounded from below

for lambda < lambda(crit) is bounded below and purely discrete, while for lambda > lambda(crit) it is unbounded from below. In the subcritical case, we prove upper and lower......

Estimation of the short-term zonal tides from UT1 observations

A new 97-term model of fortnightly and monthly zonal tides in UT1 with accuracy about 2.1 microseconds and residuals below 13 microseconds is proposed....

Neglecting uncertainty behind Allee effect estimation may generate false predictions of population extinction risk

We explore how accounting for uncertainty behind estimation of extinction thresholds arising from Allee effects (Allee thresholds) affects the probability of population extinction. Deviations from when only a point esti...
