Extrapolation of compactness on weighted mixed Lebesgue spaces
arXiv:2503.12486
Abstract
A version of the Fréchet-Kolmogorov theorem for the compactness of operators in weighted mixed Lebesgue spaces is proved and a corresponding compact extrapolation theory a la Rubio de Francia is developed. Several applications are presented too.
