A note on rank 2 diagonals | Angelo Bella
; Santi Spadaro
; | Date: |
6 Nov 2018 | Abstract: | We solve two questions regarding spaces with a ($G_delta$)-diagonal of rank
2. One is a question of Basile, Bella and Ridderbos regarding weakly Lindel"of
spaces with a $G_delta$-diagonal of rank 2 and the other is a question of
Arhangel’skii and Bella asking whether every space with a diagonal of rank 2
and cellularity continuum has cardinality at most continuum. | Source: | arXiv, 1811.2386 | Services: | Forum | Review | PDF | Favorites |
