Cardinal sequences of LCS spaces under GCH
Let C(α) denote the class of all cardinal sequences of length α associated with compact scattered spaces. Also put Cλ(α) = {f ∈ C(α) : f(0) = λ = min[f(β) : β < α]}. If λ is a cardinal and α < λ++ is an ordinal, we define Dλ(α) as follows: if λ = ω, Dω(α) = {f ∈ {ω, ω1} : f(0) = ω}, and if λ is uncountable, Dλ(α) = {f ∈ {λ, λ} : f(0) = λ, f−1{λ} is < λ-closed and successor-closed in α}. We show...
متن کاملThin-tall Spaces and Cardinal Sequences
We are concerned with a series of problems regarding the existence of Hausdorff scattered spaces of a given Cantor-Bendixson height and with a given associated cardinal sequence.
متن کاملCardinal Sequences and Cohen Real Extensions
We show that if we add any number of Cohen reals to the ground model then, in the generic extension, a locally compact scattered space has at most (2 ℵ0) V many levels of size ω. We also give a complete ZF C characterization of the cardinal sequences of regular scattered spaces. Although the classes of the regular and of the 0-dimensional scattered spaces are different, we prove that they have ...
متن کاملChanging Cardinal Characteristics without Changing Ω-sequences or Cofinalities
We show: There are pairs of universes V1 ⊆ V2 and there is a notion of forcing P ∈ V1 such that the change mentioned in the title occurs when going from V1[G] to V2[G] for a P -generic filter G over V2. We use forcing iterations with partial memories. Moreover, we implement highly transitive automorphism groups into the forcing orders.
متن کاملAdding Many Ω-sequences to a Singular Cardinal
In order to present this result, we approach it by proving some preliminary theorems about different forcings which capture the main ideas in a simpler setting. For the entirety of the notes we work with an increasing sequence of large cardinals 〈κn | n < ω〉 with κ =def supn<ω κn. The large cardinal hypothesis that we use varies with the forcing. A recurring theme is the idea of a cell. A cell ...
