Almost completely decomposable groups with primary regulator quotients and their endomorphism rings (Q950822)

Block rigid almost completely decomposable groups have been intensively studied because they comprise one of the few classes of torsion-free Abelian groups for which classification is feasible. The author is a leading researcher in this area, and in this paper she concentrates on an amenable subclass consisting of groups whose critical typeset is an anti-chain of ring types and whose regulator quotient is primary. She constructs and analyzes the endomorphism rings of the groups in this class.
