Separating weak partial square principles
We introduce the weak partial square principles pλ,κ and p λ,<κ, which combine the ideas of a weak square sequence and a partial square sequence. We construct models in which weak partial square principles fail. The main result of the paper is that λ,κ does not imply λ,<κ. Let λ be a regular uncountable cardinal and let κ ≤ λ be a nonzero cardinal. Recall the square principle λ,κ (respectively ...
متن کاملSeparating partial normality classes with weighted composition operators
In this article, we discuss measure theoretic characterizations for weighted composition operators in some operator classes on $L^{2}(Sigma)$ such as, $n$-power normal, $n$-power quasi-normal, $k$-quasi-paranormal and quasi-class$A$. Then we show that weighted composition operators can separate these classes.
متن کاملDiamond, Gch and Weak Square
Shelah proved recently that if κ > ω and S ⊆ κ+ is a stationary set of ordinals of cofinality different from cf(κ), then 2κ = κ+ implies ♦κ+ (S). We show that for singular κ, an elaboration on his argument allows us to derive ♦κ+ (T ) from 2κ = κ+ + κ where T = {δ < κ+ | cf(δ) = cf(κ)}. This gives a strong restriction on the existence of saturated ideals on κ+.
متن کاملChang's Conjecture and weak square
We investigate how weak square principles are denied by Chang’s Conjecture and its generalizations. Among other things we prove that Chang’s Conjecture does not imply the failure of ω1,2, i.e. Chang’s Conjecture is consistent with ω1,2.
متن کاملA Very Weak Square Principle
In this paper we explicate a very weak version of the principle discovered by Jensen who proved it holds in the constructible universe L. This principle is strong enough to include many of the known applications of , but weak enough that it is consistent with the existence of very large cardinals. In this section we show that this principle is equivalent to a common combinatorial device, which ...
