On positive and constructive groups
N. G. Khisamiev East Kazakhstan State Technical University named after D. Serikbayev, Ust-Kamenogorsk, Kazakhstan
Abstract:
Considering a group with unique roots (i.e., an $R$-group), we give a sufficient condition for the existence of a positive (constructive) enumeration with respect to which the isolator of the commutant is computable. Basing on it, we prove the constructivizability of an $R$-group that admitting a positive enumeration for which the dimension of the commutant is finite. We obtain a necessary and sufficient condition of constructivizability for a torsion-free nilpotent group for which the dimension of the commutant is finite.
Keywords:
$R$-group, positive (constructive) group, positivizable (constructivizable) group, commutant, center of a group, dimension of a group, computably enumerable (computable) group.
