On a class of butler groups
Copyright policy )On a class of butler groups
Using elementary lattice theoretic and linear algebraic techniques, the authors classify up to isomorphism and up to quasi-isomorphism the strongly indecomposable Butler groups that occur as quotients of a finite rank completely decomposable torsion-free abelian group modulo a rank 1 pure subgroup.
