Real interpolation of $B{_¥sigma}$ spaces (Theory of function spaces and related topics)
概要
Recently, Bσ spaces are defined by some authors in various context. The goal of this note is to provide an equivalent expression based on the work by Feichtinger as well as the one by Alvarez, Guzmán-Partida and Lakey. The description of the real interpolation of Bσ spaces is obtained as an application, which will supplement the results by Nakai and Sobukawa in their 2016 paper.
