End Point Results for Estimates of Singular Values of Singular Integral Operators,ideals) is well understood when the index, p, is greater than one. Here we offer results for the case p = 1. The simplest example, when the integral operator is the Hilbert transform, is atypical because of the algebraic simplicity of the kernel. Our methods are designed for more general kernels.作者: 強(qiáng)有力 時(shí)間: 2025-3-23 06:59 作者: 果仁 時(shí)間: 2025-3-23 11:24
