Computing unit groups of curves

open access: yesJournal of Symbolic Computation, 2021
The group of units modulo constants of an affine variety over an algebraically closed field is free abelian of finite rank. Computing this group is difficult but of fundamental importance in tropical geometry, where it is desirable to realize intrinsic tropicalizations.

Symmetric core-cohesive blockmodel in preschool children's interaction networks.

open access: yesPLoS ONE, 2020
Researchers have extensively studied the social mechanisms that drive the formation of networks observed among preschool children. However, less attention has been given to global network structures in terms of blockmodels.

Group algebras with an Engel group of units [PDF]

open access: yesJournal of the Australian Mathematical Society, 2006
AbstractLet F be a field of characteristic p and G a group containing at least one element of order p. It is proved that the group of units of the group algebra FG is a bounded Engel group if and only if FG is a bounded Engel algebra, and that this is the case if and only if G is nilpotent and has a normal subgroup H such that both the factor group G/H

Group Identities on Units of Group Algebras

open access: yesJournal of Algebra, 2000
Let \(U\) be the group of units of the group algebra \(FG\), where \(G\) is a group and \(F\) is a field. This paper is concerned with determining when \(U\) satisfies a group identity. If \(G\) is torsion, then this question was settled in recent years, thereby yielding an affirmative solution to Hartley's problem.

Managing the risk of comparing estimated breeding values across flocks or herds through connectedness: a review and application

open access: yesGenetics Selection Evolution, 2007
Comparing predicted breeding values (BV) among animals in different management units (e.g. flocks, herds) is challenging if units have different genetic means.
