BIU seminar in Set Theory
Speaker: Bill Chen (BGU)
There will be two talks: November 27 and December 4.
First talk: A small Dowker space, part 1
Abstract. A topological space is said to be “Dowker” if it is normal but its product with the unit interval is not normal. In this lecture, we shall present a construction, due to Balogh, of a Dowker space of size continuum.
Second talk: A small Dowker space, part 2
Abstract. Last week, we presented an approach for constructing a Dowker space of size continuum, ending up with a statement of a lemma that would yield such a space. In this talk, we shall prove this lemma.
