On verbally closed subgroups of free solvable groups

TL;DR

This paper investigates the properties of verbally closed subgroups within free solvable groups, establishing conditions under which such subgroups are retracts and algebraically closed, advancing understanding of subgroup structure in these groups.

Contribution

It provides new sufficient conditions for verbally closed subgroups to be retracts and algebraically closed in free solvable groups, enhancing subgroup classification.

Findings

Verbal closure implies retracts under certain conditions

Conditions identified for algebraic closure in free solvable groups

Advances understanding of subgroup structure in solvable groups

Abstract

We study verbally closed subgroups of free solvable groups. A number of results is proved that give sufficient conditions under whose a verbally closed subgroup is turned to be a retract and so algebraically closed of the full group.
