On the generalized Riemann–Hilbert problem with irregular singularities [PDF]

, 2006
We study the generalized Riemann–Hilbert problem, which extends the classical Riemann–Hilbert problem to the case of irregular singularities. The problem is stated in terms of generalized monodromy data which include the monodromy representation, the ...

Monodromy representations of Jordan-Pochhammer systems

Современная математика: Фундаментальные направления
In this paper, we consider Burau representations of braid groups and Gassner representations of pure braid groups, and their realization as monodromy representations of Jordan-Pochhammer systems with suitable parameters.

A Riemann-Hilbert Problem for the Moisil-Teodorescu System [PDF]

, 2019
In a bounded domain with smooth boundary in \R^3 we consider the stationary Maxwell equations for a function u with values in \R^3 subject to a nonhomogeneous condition (u, v)_x = u_0 on the boundary, where v is a given vector field and u_0 a function on

A Riemann-Hilbert problem from stability conditions

, 2019
Given an algebra $A$ and a set of automorphisms, one can define a Riemann-Hilbert (RH) problem, aimed to find meromorphic connections on the $\mathrm{Aut}(A)$-principl bundle over $\bC$ with prescribed generalised monodromy.

Optical solitons and their propagations in a time-varying coefficient modified nonlinear Schrödinger equation with non-zero boundary conditions via Riemann–Hilbert method

Results in Physics
In this article, a time-varying coefficient modified nonlinear Schrödinger equation (tvcmNLSE) with non-zero boundary conditions (NZBCs) at infinity, phase term of which contains time-varying coefficients, is proposed to describe the nonlinear ...

Riemann-Hilbert problem associated with Angelesco systems [PDF]

, 2007
Angelesco systems of measures with Jacobi type weights are considered. For such systems, strong asymptotic development expressions for sequences of associated Hermite-Pad´e approximants are found.

Dynamical Behavior Analysis of Generalized Chen–Lee–Liu Equation via the Riemann–Hilbert Approach

Fractal and Fractional
In this paper, we investigate the dynamics of the generalized Chen–Lee–Liu (gCLL) equation utilizing the Riemann–Hilbert method to derive its N-soliton solution.

A Hilbert Boundary Value Problem for Generalised Cauchy-Riemann Equations

, 2017
We elaborate a boundary Fourier method for studying an analogue of the Hilbert problem for analytic functions within the framework of generalised Cauchy-Riemann equations.
