Riemann-Hilbert-Probleme

2005
Die Randwertaufgaben fur die Cauchy-Riemannschen Differentialgleichungen sind einerseits grundlegend fur viele Anwendungen, zum anderen enthullen sie tiefe, uberraschende Zusammenhange zwischen topologischen Invarianten und algebraischen Invarianten stetiger linearer Abbildungen.

Nonlinear Riemann ‐ Hilbert Problems without Transversality

Mathematische Nachrichten, 1997
AbstractNonlinear Riemann ‐ Hilbert problems (RHP) generalize two fundamental classical problems for complex analytic functions, namely: 1. the conformal mapping problem, and 2. the linear Riemann ‐ Hilbert problem. This paper presents new results on global existence for the nonlinear (RHP) in doubly connected domains with nonclosed restriction curves ...

ASYMPTOTIC EXPANSIONS FOR RIEMANN–HILBERT PROBLEMS

Analysis and Applications, 2008
Let Γ be a piecewise smooth contour in ℂ, which could be unbounded and may have points of self-intersection. Let V(z, N) be a 2 × 2 matrix-valued function defined on Γ, which depends on a parameter N. Consider a Riemann–Hilbert problem for a matrix-valued analytic function R(z, N) that satisfies a jump condition on the contour Γ with the jump matrix V(

Riemann-Hilbert problems

2016
In his famous dissertation from 1851, Bernhard Riemann (1826–1866) formulated the following problem: In a given bounded domain of the complex plane, determine a holomorphic function, if a relation is prescribed between the boundary values of its real part and its imaginary part. In the case of a linear relation this problem was first considered in 1904

Separation Principles and Riemann-Hilbert Problems

Computational Methods and Function Theory, 2003
Let \(w_\pm\) be the holomorphic functions on the unit disk \(D\subset \mathbb{C}\) and let \(M_t=\{x+if(t,x)\},\;x\in R,\;t\in\partial D\) where \(f(t,x)\) is real-valued. For a given subset \(A\) in the Hardy space \(H^1\) denote by \(A_+=\{w_+\in A, v_+(t)\geq f(t,u_+(t))\;a.e.\;on\;\partial D\}\) and \(A_-=\{w_-\in A, v_-(t)\geq f(t,u_-(t))\;a.e ...
