Absolutely Closed Groups in the Class of $2$-Step Nilpotent Torsion-Free Groups
S. A. Shakhova Altai State University, Barnaul
Abstract:
It is proved that divisible groups and only these groups are absolutely closed (with respect to the operator of dominion) in the class of $2$-step nilpotent torsion-free groups. It is established that the additive group of the rationals is $1$-closed in an arbitrary quasivariety of nilpotent torsion-free groups and $3$-closed in an arbitrary quasivariety of $2$-step nilpotent torsion-free groups.
Keywords:
quasivariety, divisible group, torsion-free group, dominion, absolutely closed group, $2$-step nilpotent torsion-free group.
