Generalization of I.Vekua's integral representations of holomorphic functions and their application to the Riemann–Hilbert–Poincaré problem [PDF]

open access: yesJournal of Function Spaces and Applications, 2011
I. Vekua’s integral representations of holomorphic functions, whose m-th derivative (m≥0) is Hӧlder-continuous in a closed domain bounded by the Lyapunov curve, are generalized for analytic functions whose m-th derivative is representable by a Cauchy ...

A Class of Nonlinear Generalized Riemann-Hilbert-Poincaré Problems for Holomorphic Functions

open access: bronzeZeitschrift für Analysis und ihre Anwendungen, 1987
By means of the theory of pseudo-monotone operators the existence of a solution of a class of nonlinear generalized Riemann-Hilbert-Poincaré problems for a holomorphic function in the unit disk is proved.

Inverse Scattering Transform for the Generalized Derivative Nonlinear Schrödinger Equation via Matrix Riemann–Hilbert Problem [PDF]

open access: goldMathematical Problems in Engineering, 2022
The inverse scattering transformation for a generalized derivative nonlinear Schrödinger (GDNLS) equation is studied via the Riemann–Hilbert approach. In the direct scattering process, we perform the spectral analysis of the Lax pair associated with a 2 × 2

Riemann-Hilbert Boundary Value Problem for Generalized Analytic Functions in Smirnov Classes [PDF]

open access: green, 2014
The Riemann-Hilbert boundary value problem for generalized analytic functions in Smirnov classes is under consideration. The domain is supposed simply connected with Lyapunov or Radon boundary without cusps. In the work the special representation for generalized analytic functions of Smirnov classes is built.

Riemann-Hilbert boundary value problems in BMO classes for generalized analytic functions

open access: bronzeВладикавказский математический журнал, 2011
В работе рассматривается разрешимость краевой задачи Римана - Гильберта в классе BMO для обобщенных аналитических функций в предположении, что коэффициент краевого условия принадлежит пространству мультипликаторов класса BMO. Ранее автором построены примеры, когда задача с неотрицательным индексом в такой наиболее стественной постановке неразрешима в ...

Riemann–Hilbert problems for null-solutions to iterated generalized Cauchy–Riemann equations in axially symmetric domains

open access: bronzeComputers & Mathematics with Applications, 2016
We consider Riemann-Hilbert boundary value problems (for short RHBVPs) with variable coefficients for axially symmetric poly-monogenic functions, i.e., null-solutions to iterated generalized Cauchy-Riemann equations, defined in axially symmetric domains.
