The pseudorational rank of an abelian group
Siberian Mathematical Journal, 2005Summary: We study finite-rank torsion-free Abelian groups and quotient divisible mixed groups. We consider the pseudorational rank, a new invariant for finite-rank torsion-free groups which was introduced by \textit{A. A. Fomin} [in Trends in Mathematics, 87-100 (1999; Zbl 0947.20037)], and establish its connection with the usual rank.

The rank of a latin square associated to an abelian group
Communications in Algebra, 2000Let be a finite abelian group, where pi (1 ≤ i ≤ r) are (not necessarily distinct) odd primes. Suppose . Using a result of Carlitz and Moser, we show that . Consequently, we prove that the rank of any Latin square associated with the group G is at least . This sharpens a result in [2].
