Correction to: “The typeset and cotypeset of a rank 2 abelian group” [PDF]
Let \(A\) be a reduced rank 2 torsion-free abelian group. Denote by \(T\) the set of types of elements of \(A\), and by \(T\mathrm{'}\) the set of types of rank 1 torsion-free factor groups of A. The author characterizes such pairs \((T,T\mathrm{'})\), and counts the number of isomorphism and quasi-isomorphism classes of rank 2 groups realizing each ...

Extensions of Abelian Groups of Finite Rank [PDF]
Every abelian group X oi finite rank arises as the middle group of an extension e: 0 -> F -> A" -> T->0 where F is free of finite rank zz and T is torsion with the p-ranks of T finite for all primes p. Given such a T and F we study the equivalence classes of such extensions which result from stipulating that two extensions e . : 0 -» F -> X. -» T -> 0,

Acentralizers of Abelian groups of rank 2
Let $G$ be a group. The Acentralizer of an automorphism $\alpha$ of $G$, is the subgroup of fixed points of $\alpha$, i.e., $C_G(\alpha)= \{g\in G \mid \alpha(g)=g\}$. We show that if $G$ is a finite Abelian $p$-group of rank $2$, where $p$ is an odd prime, then the number of Acentralizers of $G$ is exactly the number of subgroups of $G$.

ON SOME VERTEX-TRANSITIVE DISTANCE-REGULAR ANTIPODAL COVERS OF COMPLETE GRAPHS
In the present paper, we classify abelian antipodal distance-regular graphs \(\Gamma\) of diameter 3 with the following property: \((*)\) \(\Gamma\) has a transitive group of automorphisms \(\widetilde{G}\) that induces a primitive almost simple ...

On the LHC signatures of $$SU(5)\times U(1)'$$ S U ( 5 ) × U ( 1 ) ′ F-theory motivated models
We study low energy implications of F-theory GUT models based on SU(5) extended by a $$U(1)'$$ U ( 1 ) ′ symmetry which couples non-universally to the three families of quarks and leptons.
