Unit Groups of Cyclic Extensions [PDF]
LetΩbe an algebraic number field of finite degree, which we fix once for all, and letKbe a cyclic extension overΩsuch that the degree ofK/Ωis a powerof a prime numberl. It is obvious that the norm groupNK/ΩeKof the unit group ekofK, being a subgroup of the unit group e of Ω contains the groupconsisting of all-th powersof ε∈e.

A large class of sofic monoids [PDF]
We prove that a monoid is sofic, in the sense recently introduced by Ceccherini-Silberstein and Coornaert, whenever the J-class of the identity is a sofic group, and the quotients of this group by orbit stabilisers in the rest of the monoid are amenable.

Ecoindicators: An R Package for the Identification of Indicator Taxonomic Units
The sensitivity of some taxonomic groups to environmental conditions allows for their use as ecological state indicators. In ecological communities, this analysis is of interest to know which species or taxa are indicators of particular environment ...

Covariate balancing based on kernel density estimates for controlled experiments
Controlled experiments are widely used in many applications to investigate the causal relationship between input factors and experimental outcomes. A completely randomised design is usually used to randomly assign treatment levels to experimental units ...

GROUP ALGEBRAS WHOSE GROUP OF UNITS IS POWERFUL [PDF]
AbstractA p-group is called powerful if every commutator is a product of pth powers when p is odd and a product of fourth powers when p=2. In the group algebra of a group G of p-power order over a finite field of characteristic p, the group of normalized units is always a p-group. We prove that it is never powerful except, of course, when G is abelian.
