Analogs of the Prime Number Problem in a Shot Noise Suppression of the Soft-Reset Process [PDF]

open access: yesNanomaterials
The soft-reset process, or a sequence of charge emissions from a floating storage node through a transistor biased in a subthreshold bias condition, is modeled by a master (Kolmogorov–Bateman) equation.

EQUIVALENCE OF THE FREDHOLM SOLVABILITY CONDITION FOR THE NEUMANN PROBLEM TO THE COMPLEMENTARITY CONDITION

open access: yesВестник КазНУ. Серия математика, механика, информатика, 2021
The methods of complex analysis constitute the classical direction in the study of elliptic equations and mixed-type equations on the plane and fundamental results have now been obtained. In the early 60s of the last century, a new theoretical-functional

Complex Monge–Ampère equations for plurifinely plurisubharmonic functions

open access: yesIndagationes Mathematicae, 2023
This paper studies the complex Monge-Ampère equations for $\mathcal F$-plurisubharmonic functions in bounded $\mathcal F$-hyperconvex domains. We give sufficient conditions for this equation to solve for measures with a singular part.

Exact solutions of nonlinear delay reaction–diffusion equations with variable coefficients

open access: yesPartial Differential Equations in Applied Mathematics, 2021
A modified method of functional constraints is used to construct the exact solutions of nonlinear equations of reaction–diffusion type with delay and which are associated with variable coefficients.

Methods for Constructing Complex Solutions of Nonlinear PDEs Using Simpler Solutions

open access: yesMathematics, 2021
This paper describes a number of simple but quite effective methods for constructing exact solutions of nonlinear partial differential equations that involve a relatively small amount of intermediate calculations.

The Complex WKB Method for Difference Equations and Airy Functions [PDF]

open access: yesSIAM Journal on Mathematical Analysis, 2019
We consider the difference Schr{\"o}dinger equation $\psi$(z + h) + $\psi$(z -- h) + v(z)$\psi$(z) = 0 where z is a complex variable, h > 0 is a parameter, and v is an analytic function. As h $\rightarrow$ 0 analytic solutions to this equation have a standard quasiclassical behavior near the points where v(z) = $\pm$2.

Stepanov-like doubly weighted pseudo almost automorphic mild solutions for fractional stochastic neutral functional differential equations

open access: yesJournal of Inequalities and Applications, 2023
This paper first investigates the equivalence of the space and translation invariance of Stepanov-like doubly weighted pseudo almost automorphic stochastic processes for nonequivalent weight functions; secondly, based on semigroup theory, fractional ...
