Abstract

We prove pointwise convergence for the scattering data of a Dirac system of differential equations. Equivalently, we prove an analog of Carleson’s theorem on almost everywhere convergence of Fourier series for a version of the non-linear Fourier transform. Our proofs are based on the study of resonances of Dirac systems using families of meromorphic inner functions, generated by a Riccati equation corresponding to the system.

非线性傅立叶变换的点收敛性 | 数学年鉴

我们证明了狄拉克微分方程系统散射数据的点收敛性。等效地，我们证明了 Carleson 关于非线性傅里叶变换版本的傅里叶级数几乎无处不收敛的类似定理。我们的证明基于对狄拉克系统共振的研究，使用的是由与该系统相对应的里卡蒂方程所产生的并行内函数族。
