The one-point Lindelöfication of an uncountable discrete space can be surlindelöf
Oleg Okunev (2013)
Open Mathematics
Similarity:
We prove that the one-point Lindelöfication of a discrete space of cardinality ω 1 is homeomorphic to a subspace of C p (X) for some hereditarily Lindelöf space X if the axiom [...] holds.
Is the product of ccc spaces a ccc space?
Nina M. Roy (1989)
Publicacions Matemàtiques
Similarity:
In this expository paper it is shown that Martin's Axiom and the negation of the Continuum Hypothesis imply that the product of ccc spaces is a ccc space. The Continuum Hypothesis is then used to construct the Laver-Gavin example of two ccc spaces whose product is not a ccc space.
