Nonlinear interpolation and norm minimization
A. A. Zhensykbaev Al-Farabi Kazakh National University
Abstract:
We prove that the set of convolution-type functions in $\mathbb R_d$ that satisfy the interpolation conditions contains a unique function whose convolution element has the minimum $L_p$-norm. The extremal function is determined by solving a nonlinear interpolation problem. The results are applied to an operator recovery problem.
