Basic complex boundary value problems in in the upper half plane

open access: closed, 2006
In der Analysis spielen Integraldarstellungen für Funktionen eine bedeutende Rolle. Dies gilt insbesondere im Hinblick auf gewöhnliche und partielle Differentialgleichungen. Solche Differentialgleichungen wiederum tauchen bei den meisten Problemen der angewandten Mathematik auf. In der Regel werden Integraldarstellungen auf reguläre Gebiete formuliert,

Boundary value problems of integrodifferential equations under boundary conditions taking into account physical nonlinearity [PDF]

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2023
When solving integrodifferential equations under boundary conditions, taking into account physical nonlinearity, a broad class of boundary-value problems of oscillations arises associated with various boundary conditions at the edges of a flat element ...

The d-bar formalism for the modified Veselov-Novikov equation on the half-plane [PDF]

open access: yesOpuscula Mathematica, 2022
We study the modified Veselov-Novikov equation (mVN) posed on the half-plane via the Fokas method, considered as an extension of the inverse scattering transform for boundary value problems.

Hypersingular Integro-Differential Equation Containing Polynomials and Their Derivatives in Coefficients

open access: yesMathematics, 2023
A new linear integro-differential equation is considered on a closed curve located on the complex plane. The integrals in the equation are understood in the sense of a finite part, according to Hadamard.
