Optimal Histogram Filter

open access: yesДоклады Белорусского государственного университета информатики и радиоэлектроники, 2023
The article discusses a technique for constructing an optimal histogram filter and its modifications, taking into account a priori information about the expected probability distribution density.

On function field Mordell-Lang and Manin-Mumford [PDF]

open access: yes, 2015
We present a reduction of the function field Mordell-Lang conjecture to the function field Manin-Mumford conjecture, in all characteristics, via model theory, but avoiding recourse to the dichotomy theorems for (generalized) Zariski structures. In this

The discounted local limit theorems for large deviations

open access: yesLietuvos Matematikos Rinkinys, 2008
Theorems of large deviations, both in the Cramer zone and the Linnik power zones, for the normal approximation of the distribution density function of normalized sum Sv = \sum∞ k=0 vkXk, 0 < v < 1, of i.i.d.

Diophantine Undecidability of Holomorphy Rings of Function Fields of Characteristic 0 [PDF]

open access: yes, 2009
Let $K$ be a one-variable function field over a field of constants of characteristic 0. Let $R$ be a holomorphy subring of $K$, not equal to $K$. We prove the following undecidability results for $R$: If $K$ is recursive, then Hilbert's Tenth Problem is ...

On the characteristic function of a sum of M-dependent random variables

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1986
Let S=f1+f2+…+fn be a sum of 1-dependent random variables of zero mean. Let σ2=ES2, L=σ−3∑1≦i≦nE|fi|3.

Pricing Bermudan options under local L\'evy models with default [PDF]

open access: yes, 2016
We consider a defaultable asset whose risk-neutral pricing dynamics are described by an exponential L\'evy-type martingale. This class of models allows for a local volatility, local default intensity and a locally dependent L\'evy measure.

Full analysis of multi-photon pair effects in spontaneous parametric down conversion based photonic quantum information processing

open access: yesNew Journal of Physics, 2015
In spontaneous parametric down conversion (SPDC) based quantum information processing (QIP) experiments, there is a tradeoff between the coincidence count rates (i.e.

Non-uniform Estimates in the Approximation by the Irwin Law

open access: yesLithuanian Journal of Statistics, 2016
We consider an approximation of a cumulative distribution function F(x) by the cumulative distributionfunction G(x) of the Irwin law. In this case, a function F(x) can be cumulative distribution functions of sums (products) ofindependent (dependent ...
