אn -free Abelian Group with No Non-zero Homomorphism to Z Sh883
نویسنده
چکیده
We, for any natural n, construct an אn-free abelian groups which have few homomorphisms to Z. For this we use “אn-free (n+1)-dimensional black boxes”. The method is hopefully relevant to other constructions of אn-free abelian groups. I would like to thank Alice Leonhardt for the beautiful typing.

ON THE GROUPS WITH THE PARTICULAR NON-COMMUTING GRAPHS
Let $G$ be a non-abelian finite group. In this paper, we prove that $Gamma(G)$ is $K_4$-free if and only if $G cong A times P$, where $A$ is an abelian group, $P$ is a $2$-group and $G/Z(G) cong mathbb{ Z}_2 times mathbb{Z}_2$. Also, we show that $Gamma(G)$ is $K_{1,3}$-free if and only if $G cong {mathbb{S}}_3,~D_8$ or $Q_8$.
متن کاملאn-Free Modules With Trivial Duals
In the first part of this paper we introduce a simplified version of a new Black Box from Shelah [11] which can be used to construct complicated אn-free abelian groups for any natural number n ∈ N. In the second part we apply this prediction principle to derive for many commutative rings R the existence of אn-free R-modules M with trivial dual M ∗ = 0, where M∗ = Hom(M, R). The minimal size of ...
متن کاملReasonable non–Radon–Nikodym idealss
For any abelian Polish σ-compact group H there exist an Fσ ideal Z ⊆ P (N) and a Borel Z -approximate homomorphism f : H → HN which is not Z -approximable by a continuous true homomorphism g : H → HN .
متن کاملSome Non-trivial Cocycles
For each locally compact non-compact c-compact Abelian group G whose dual is an I-group and each compact Abelian group ,?J such that there is a one-to-one continous homomorphism from G onto a dense subgroup of Z, we show the existence of cocycles on Z whose associated unitary representations of G have purely singular continuous spectrum, as well as the existence of cocycles on Z whose associate...
متن کاملJa n 20 09 Large zero - free subsets of Z / p Z
A finite subset A of an abelian group G is said to be zero-free if the identity element of G cannot be written as a sum of distinct elements from A. In this article we study the structure of zero-free subsets of Z/pZ the cardinality of which is close to largest possible. In particular, we determine the cardinality of the largest zero-free subset of Z/pZ, when p is a sufficiently large prime. Fo...
