在这篇文章中,这是一个扩展帐户的讲座由第一作者在E1埃斯科里亚尔在1996年6月,我们讨论了国家的发挥在该地区的逐点反演和本地化的球面傅立叶积分R n。旧的结果是没有证明,而我们包括证明(严格或启发式)的一些较新的定理。我们要感谢M。天哪,C。凯尼格湾玛丽埃塔角Thiele和A.巴尔加斯在讨论和合作中产生的贡献。对于f~ L2(Rn,n> 2),我们构造了它的Fourier变换f(~)= ff(x)e-2nix '~ dx作为L2的一员,并给出了它的部分球面Fourier逆积分
In this article, which is an expanded account of the lecture given by the first author at E1 Escorial in June 1996, we discuss the state of play in the area of pointwise inversion and localisation of spherical Fourier Integrals in R n. The older results are stated without proofs, while we include proofs (rigorous or heuristic) of some of the newer theorems. We wish to thank M. Christ, C. Kenig, G. Marietta, C. Thiele, and A. Vargas for contributions arising in discussions and collaborations. For f~ L2 (Rn), n> 2, we form its Fourier transform f (~)= ff (x) e-2nix'~ dx as a member of L 2, and the partial spherical inverse Fourier Integrals
