On Complex Analytic Tools, and the Holomorphic Rotation Methods
摘要
An extended holomorphic Radon transform enables a “method of rotations” to lift one dimensional adapted nonlinear holomorphic analysis tools to higher dimensions. In particular the various multiscale orthogonal bases of holomorphic functions in Hardy spaces in one dimension give rise to orthogonal bases of Harmonic functions on higher dimensional half spaces. We provide an overview of recent progress in nonlinear approximation using holomorphy, and discuss their extension to high dimension through the Radon transform.
