Singular integral operators in the case of a piecewise Lyapunov contour

Acta et commentationes: Ştiinţe Exacte şi ale Naturii, 2022
The article attempts to present the results obtained by the author in recent years (in a number of cases with some additions) on the theory of singular integral equations and Riemann boundary value problems in the case of a piecewise Lyapunov contour.

Criterion of Uniform Invertibility of Regular Approximations of One-Dimensional Singular Integral Operators on a Piecewise-Lyapunov Contour

Владикавказский математический журнал, 2019
Работа продолжает исследования в области критериев применимости к полным сингулярным интегральным операторам приближенных методов по семействам сильно аппроксимирующих их операторов с "вырезанной" особенностью ядра Коши. Рассматривается случай полного сингулярного интегрального оператора с непрерывными коэффициентами, действующего в $L\sb{p ...

Structured chaos shapes spike-response noise entropy in balanced neural networks. [PDF]

Front Comput Neurosci, 2014
Large networks of sparsely coupled, excitatory and inhibitory cells occur throughout the brain. A striking feature of these networks is that they are chaotic. How does this chaos manifest in the neural code?

A finite state projection algorithm for the stationary solution of the chemical master equation [PDF]

, 2017
The chemical master equation (CME) is frequently used in systems biology to quantify the effects of stochastic fluctuations that arise due to biomolecular species with low copy numbers.

Zonal Jets as Transport Barriers in Planetary Atmospheres [PDF]

, 2008
The connection between transport barriers and potential vorticity (PV) barriers in PV-conserving flows is investigated with a focus on zonal jets in planetary atmospheres. A perturbed PV-staircase model is used to illustrate important concepts. This flow

On the symbol of singular operators in the case of contour with corner points

Acta et Commentationes: Ştiinţe Exacte şi ale Naturii
This paper proposes a method for constructing a symbol for singular integral operators in the case of a piecewise Lyapunov contour. The definition of the symbol function involves numbers that characterize the space in which the research is being carried

Perturbation of singular integral operators with piecewise continuous coefficients

Acta et Commentationes: Ştiinţe Exacte şi ale Naturii
In the paper it is shown that the property of singular integral operators with piecewise continuous coefficients to be Noetherian is stable with respect to their perturbation with certain non-compact operators. An example is constructed showing that the

Moments and Lyapunov exponents for the parabolic Anderson model

, 2013
We study the parabolic Anderson model in $(1+1)$ dimensions with nearest neighbor jumps and space-time white noise (discrete space/continuous time). We prove a contour integral formula for the second moment and compute the second moment Lyapunov exponent.
