On the Root-class Residuality of HNN-extensions of Groups
Let K be an arbitrary root class of groups. This means that K contains at least one non-unit group, is closed under taking subgroups and direct products of a finite number of factors and satisfies the Gruenberg condition: if 1 ≤ Z ≤ Y ≤ X is a subnormal series of a group X such that X/Y ∈ K and Y/Z...
