Stationary and closed rainbow subsets
نویسندگان
چکیده
We study the structured rainbow Ramsey theory at uncountable cardinals. When compared to usual theory, variation focuses on finding a subset that not only is of certain cardinality but also satisfies structural constraints, such as being stationary or closed in its supremum. In process dealing with cardinals greater than $\omega_1$, we uncover some connections between versions Chang's Conjectures and instances partition relations, addressing question raised \cite{zhang}.

SOME REMARKS ON GENERALIZATIONS OF MULTIPLICATIVELY CLOSED SUBSETS
Let R be a commutative ring with identity and Mbe a unitary R-module. In this paper we generalize the conceptmultiplicatively closed subset of R and we study some propertiesof these genaralized subsets of M. Among the many results in thispaper, we generalize some well-known theorems about multiplicativelyclosed subsets of R to these generalized subsets of M. Alsowe show that some other well-kno...
متن کاملClosed description of stationary flames
The problem of non-perturbative description of stationary flames with arbitrary gas expansion is considered. A general method for deriving equations for the flame front position is developed. On the basis of the Thomson circulation theorem an implicit integral of the flow equations is constructed. With the help of this integral the flow structure near the flame front is determined, and a closed...
متن کاملInert Module Extensions, Multiplicatively Closed Subsets Conserving Cyclic Submodules and Factorization in Modules
Introduction Suppose that is a commutative ring with identity, is a unitary -module and is a multiplicatively closed subset of . Factorization theory in commutative rings, which has a long history, still gets the attention of many researchers. Although at first, the focus of this theory was factorization properties of elements in integral domains, in the late nineties the theory was gener...
متن کاملIntervals in Lattices of -Meet-Closed Subsets
We study abstract properties of intervals in the complete lattice of all meet-closed subsets ( -subsemilattices) of a -(meet-)semilattice S, where is an arbitrary cardinal number. Any interval of that kind is an extremally detachable closure system (that is, for each closed set A and each point x outside A, deleting x from the closed set generated by A and x leaves a closed set). Such closure s...
متن کاملForcing closed unbounded subsets of א
1. Introduction Suppressing some important technical hypotheses for the moment, the project under-taken in this paper is this: Given a tree T of height and cardinality ω 1 , construct (uniformly in T) a subset S T ⊆ ℵ ω 1 +1 such that, if W is an outer model of V having the same ω 1 , ℵ ω 1 , and ℵ ω 1 +1 in which S T has a closed unbounded (club) subset, then T has a cofinal branch in W. Conve...
