As a special case of perspective R-modules, an Abelian goup is called perspective if isomorphic summands have a common complement. In this paper we describe many classes of such groups.

Riemann surfaces with a quasi large abelian group of automorphisms
In this work we classify all Riemann surfaces having a quasi large abelian group of automorphisms, i.e. having an abelian group of automorphisms of order strictly bigger than 2(g−1), where g denotes the genus of the Riemann surface.

When the theory of groups was first introduced, the attention was on finite groups. Now, the infinite abelian groups have some into their own. the results obtained in infinite abelian groups are very interesting and penetrating in other branches of Mathematics.
