Groups and Several Equations in one Variable

Clifford, Andrew (World Scientific Publishing, 2001)

This paper addresses the question of simultaneously solving a set of equations in one variable over torsion-free groups.

The Group <G,t|e> When G is Torsion-Free

Clifford, Andrew; Goldstein, Richard Z. (Elsevier, 2001)

In this paper we discuss classes of nontrivial elements in the group with a relative presentation <G, t \e >, where G is torsion free and e is solvable over G.
