On $ω$ -categorical groups and rings with NIP

Krzysztof Krupinski

We show that $ω$ -categorical rings with NIP are nilpotent-by-finite. We prove that an $ω$ -categorical group with NIP and fsg is nilpotent-by-finite. We also notice that an $ω$ -cate…

On relationships between algebraic properties of groups and rings in some model-theoretic contexts

Krzysztof Krupinski

We study relationships between certain algebraic properties of groups and rings definable in a first order structure or $*$ -closed in a compact $G$ -space. As a consequence, we obta…

Small, $nm$ -stable compact $G$ -groups

Krzysztof Krupinski, Frank Olaf Wagner

We prove that if $(H, G)$ is a small, $nm$ -stable compact $G$ -group, then $H$ is nilpotent-by-finite, and if additionally $\NM(H) \leq ω$, then $H$ is abelian-by-finite. Both result…
