Title: Partitioning the real line into Borel sets
Author: Brian, Will
Date Created: 2023
Subjects--Topical: Analytic functions, Borel sets
Description: For which infinite cardinals κ is there a partition of the real line R into precisely κ Borel sets? Work of Lusin, Souslin, and Hausdorff shows that R can be partitioned into ℵ1 Borel sets. But other than this, we show that the spectrum of possibl...
