Killing Luzin and Sierpinski Sets
نویسنده
چکیده
We will kill the old Luzin and Sierpinski sets in order to build a model where U (M) = U (N) = ℵ 1 and there are neither Luzin nor Sierpinski sets. Thus we answer a question of J. Steprans, communicated by S. Todorcevic on route from Evans to MSRI.

The original theme of the paper is the existence proof of “there is η̄ = 〈ηα : α < λ〉 which is a (λ, J)-sequence for Ī = 〈Ii : i < δ〉, a sequence of ideals”. This can be thought of as a generalization to Luzin sets and to Sierpinski sets, but for the product ∏ i<δ Dom(Ii), the existence proofs are related to pcf. The second theme is when does a Boolean algebra B have a free caliber λ (i.e. if X ...

متن کاملOn Separable Supports of Borel Measures
Some properties of Borel measures with separable supports are considered. In particular, it is proved that any σ-finite Borel measure on a Suslin line has a separable supports and from this fact it is deduced, using the continuum hypothesis, that any Suslin line contains a Luzin subspace with the cardinality of the continuum. Let E be a topological space. We say that the space E has the propert...

Let f be a Borel measurable mapping of a Luzin (i.e. absolute Borel metric) space L onto a metric space M such that f(F ) is a Borel subset of M if F is closed in L. We show that then f−1(y) is a Kσ set for all except countably many y ∈M , that M is also Luzin, and that the Borel classes of the sets f(F ), F closed in L, are bounded by a fixed countable ordinal. This gives a converse of the cla...
متن کاملSome Pathological Sets in Special Model of Set Theory
We Produce a model of ZF+DC in which there are Bernstein sets, Luzin sets, and Sierpinski sets, but there is no Vitali sets and hence no Hamel basis. Definition. • B ⊂ ωω is called Bernstein iff B ∩ P 6= ∅ 6 = P \ B for all perfect P ⊂ ωω. • Letting E0 ⊂ (ωω)2 be the Vitali equivalence relation defined by xE0y iff ∃n0∀n ≥ n0, x(n) = y(n), V ⊂ ωω is called Vitali if V picks exactly one element f...
