圆内逆不变矩阵的Riemann-Hilbert分解

Riemann-Hilbert factorization of matrices invariant under inversion in a circle

Hideshi Yamane

摘要:

本文考虑单位圆内具有某种求逆不变性的矩阵函数。如果这样的函数在单位圆上满足正性假设,则在其Riemann-Hilbert(Wiener-Hopf)分解中只出现零部分指标。它包含了一类Riemann-Hilbert边值问题的唯一可解性。它包括与聚焦/散焦可积离散非线性薛定谔方程的逆散射变换有关的方程。

英文摘要:

We consider matrix functions with certain invariance under inversion in the unit circle. If such a function satisfies a positivity assumption on the unit circle, then only zero partial indices appear in its Riemann-Hilbert (Wiener-Hopf) factorization. It implies the unique solvability of a certain class of Riemann-Hilbert boundary value problems. It includes the ones associated with the inverse scattering transform of the focusing/defocusing integrable discrete nonlinear Schrödinger equations.
