ATOMS IN CI-ALGEBRAS AND SINGULAR CI-ALGEBRAS
Biao Long Meng · Scientiae mathematicae Japonicae · 2010
In the present paper we continue to study CI-algebras. At first we in- troduce the notion of atoms in CI-algebras and investigate its elementary properties. Next we introduce the notion of singular CI-algebras and give a number of its proper- ties. Especially we discuss relations between singular CI-algebras and Abelian groups.
