Nonreflecting Stationary Sets in Pκλ
نویسنده
چکیده
Let κ be a regular uncountable cardinal and λ ≥ κ. The principle of stationary reflection for Pκλ has been successful in settling problems of infinite combinatorics in the case κ = ω1. For a greater κ the principle is known to fail at some λ. This note shows that it fails at every λ if κ is the successor of a regular uncountable cardinal or κ is countably closed.

Nowhere Precipitousness of the Non - Stationary Ideal Over
We prove that if λ is a strong limit singular cardinal and κ a regular uncountable cardinal < λ, then NSκλ, the non-stationary ideal over Pκλ, is nowhere precipitous. We also show that under the same hypothesis every stationary subset of Pκλ can be partitioned into λ disjoint stationary sets.
متن کاملOn Reflection of Stationary Sets in Pκλ
Let κ be an inaccessible cardinal, and let E0 = {x ∈ Pκκ : cf λx = cf κx} and E1 = {x ∈ Pκκ : κx is regular and λx = κx }. It is consistent that the set E1 is stationary and that every stationary subset of E0 reflects at almost every a ∈ E1.
متن کاملFat sets and saturated ideals
We strengthen a theorem of Gitik and Shelah [6] by showing that if κ is either weakly inaccessible or the successor of a singular cardinal and S is a stationary subset of κ such that NSκ S is saturated then κ \S is fat. Using this theorem we derive some results about the existence of fat stationary sets. We then strengthen some results due to Baumgartner and Taylor [2], showing in particular th...
متن کاملOn the intersection of sets of incoming and outgoing waves
In the neighborhood of a boundary point, the solution of a first order symmetric homogenous hyperbolic system is conveniently decomposed into fundamental waves solution, which are readily classified as outgoing, incoming and stationary or tangential. Under broad hypothesis, we show that the spans of the sets of outgoing and incoming waves have nontrivial intersection. Under these conditions, lo...
متن کاملToward the Consistency Strength of Stationary Set Reflection on Small Cardinals
OF THE DISSERTATION Toward the Consistency Strength of Stationary Set Reflection on Small Cardinals By Cynthia Northrup Doctor of Philosophy in Mathematics University of California, Irvine, 2015 Professor Dr. Martin Zeman, Chair A set S ⊆ ω3 is stationary in ω3 if it intersects all closed and unbounded subsets in ω3. We say that S reflects below ω3 if there is some α < ω3 for which S ∩ α is sta...
