First non-abelian cohomology of topological groups II
In this paper we introduce a new definition of the first non-abelian cohomology of topological groups. We relate the cohomology of a normal subgroup $N$ of a topological group $G$ and the quotient $G/N$ to the cohomology of $G$. We get the inflation-restriction exact sequence. Also, we obtain a seven-term exact cohomology sequence up to dimension 2. We give an interpretation of the first non-a...
متن کاملComputable Ordered Abelian Groups and Fields
We present transformations of linearly ordered sets into ordered abelian groups and ordered fields. We study effective properties of the transformations. In particular, we show that a linear order L has a ∆2 copy if and only if the corresponding ordered group (ordered field) has a computable copy. We apply these codings to study the effective categoricity of linear ordered groups and fields.
متن کاملThe computable dimension of ordered abelian groups
Let G be a computable ordered abelian group. We show that the computable dimension of G is either 1 or ω, that G is computably categorical if and only if it has finite rank, and that if G has only finitely many Archimedean classes, then G has a computable presentation which admits a computable basis.
متن کاملAbelian topological groups without irreducible Banach representations
We exhibit abelian topological groups admitting no nontrivial strongly continuous irreducible representations in Banach spaces. Among them are some abelian Banach–Lie groups and some monothetic subgroups of the unitary group of a separable Hilbert space.
متن کاملTopological Abelian Groups with Ordered Norms
The purpose of this paper is to study Abelian groups with a norm whose values are in another Abelian group having an order relation. Postulates on the ordering are given which are sufficient for the space to be a topological group under the neighborhood system of this norm. It is seen that the added assumption that the ordering is Archimedian implies the space is a subset of a normed linear spa...
