-torsion free Acts Over Monoids
In this paper firt of all we introduce a generalization of torsion freeness of acts over monoids, called -torsion freeness. Then in section 1 of results we give some general properties and in sections 2, 3 and 4 we give a characterization of monoids for which this property of their right Rees factor, cyclic and acts in general implies some other properties, respectively.

متن کاملDegrees of orders on torsion-free Abelian groups
We show that if H is an effectively completely decomposable computable torsion-free abelian group, then there is a computable copy G of H such that G has computable orders but not orders of every (Turing) degree.
متن کاملThe adjunction problem over torsion-free groups.
We prove injectivity and relative asphericity for "layered" systems of equations over torsion-free groups, when the exponent matrix is invertible over Z.
متن کاملEquations over Torsion-free Groups Summary Klyachko's Methods and the Solution of Equations over Torsion-free Groups
SUMMARY The question we are concerned with here is the following : Let G be a torsion-free group and consider the free product Ghti of G with an innnite cyclic group (generator t). Let w be an element of Ghti?G and hhwii denote the normal closure of w in G hti, then is the natural homomorphism G ! G hti hhwii injective?
