For a group G that is limit over Droms RAAGs such has trivial center, we show Σ1(G)=∅=Σ1(G,Q). H finitely presented residually RAAG calculate Σ1(H) and Σ2(H)dis. In addition, obtain necessary condition for [χ] to belong Σn(H).

A result of Bridson, Howie, Miller and Short states that if $S$ is a subgroup type $FP_{n}(\mathbb{Q})$ the direct product $n$ limit groups over free groups, then virtually groups. Furthermore, they characterise finitely presented residually In this paper these results are generalised to Droms right-angled Artin RAAGs with property all their generated subgroups again RAAGs. addition, we show co...

The Dynamic Host Configuration Protocol for IPv6 (DHCP) enables DHCP servers to pass configuration parameters such as IPv6 network addresses to IPv6 nodes. It offers the capability of automatic allocation of reusable network addresses and additional configuration flexibility. This protocol is a stateful counterpart to "IPv6 Stateless Address Autoconfiguration" [20], and can be used separately o...

We show that a group admits a planar, finitely generated Cayley graph if and only if it admits a special kind of group presentation we introduce, called a planar presentation. Planar presentations can be recognised algorithmically. As a consequence, we obtain an e↵ective enumeration of the planar Cayley graphs, yielding in particular an a rmative answer to a question of Droms et al. asking whet...

Biological aging is characterized by a progressive accumulation of oxidative damage and decreased endogenous antioxidant defense mechanisms. The production of oxidants by normal metabolism damages proteins, lipids, and nucleotides, which may contribute to cognitive impairment. In this study 36 dogs were randomly divided into four groups and fed croquettes of different compositions for 6 months....

We show that a group admits a planar, finitely generated Cayley graph if and only if it admits a special kind of group presentation we introduce, called a planar presentation. Planar presentations can be recognised algorithmically. As a consequence, we obtain an effective enumeration of the planar Cayley graphs, yielding in particular an affirmative answer to a question of Droms et al. asking w...
