Abstract: | It is proved that any Σ-group, which is a special elongation of a totally projective abelian p-group by a p ω+1-projective abelian p-group, is totally projective. In particular, each p ω+1-projective abelian Σ-p-group is a direct sum of countable p-groups of lengths not exceeding ω + 1. This strengthens our recent result published in Comment. Math. Univ. St. Pauli (2006). Published in Lietuvos Matematikos Rinkinys, Vol. 46, No. 2, pp. 180–185, April–June, 2006. |
