On the Property “sep” of Partial Orderings
A partial ordering P has the property SEP (or SEP(P )), if, for a sufficiently large regular cardinal χ, the family of elementary submodels of H(χ) of cardinality א1 with the property that [M ]א0 ∩M is cofinal subset (with respect to ⊆) of [M ]א0 and P ∩M ≤σ P , is cofinal (also with respect to ⊆) in [H(χ)]א1 (see Proposition 2 below). We describe, in section 1, against which historical backgro...
متن کاملFree Lattice Ordered Groups and the Topology on the Space of Left Orderings of a Group
For any left orderable group G, we recall from work of McCleary that isolated points in the space LO(G) correspond to basic elements in the free lattice ordered group F (G). We then establish a new connection between the kernels of certain maps in the free lattice ordered group F (G), and the topology on the space of left orderings LO(G). This connection yields a simple proof that no left order...
متن کاملOn spaces of Conradian group orderings
We classify C-orderable groups admitting only finitely many C-orderings. We show that if a C-orderable group has infinitely many C-orderings, then it actually has uncountably many C-orderings, and none of these is isolated in the space of C-orderings. As a relevant example, we carefully study the case of Baumslag-Solitar’s group B(1, 2). We show that B(1, 2) has four C-orderings, each of which ...

15 صفحه اولOn semi-$Pi$-property of subgroups of finite group
Let $G$ be a group and $H$ a subgroup of $G$. $H$ is said to have semi-$Pi$-property in $G$ if there is a subgroup $T$ of $G$ such that $G=HT$ and $Hcap T$ has $Pi$-property in $T$. In this paper, investigating on semi-$Pi$-property of subgroups, we shall obtain some new description of finite groups.
