Abstract
In this paper, we introduce the concepts of product and direct
sum, star projective and star injective in $H_v$-modules. We
investigate generalizations of some notions in homological algebra
to prove the five lemma and star projective and star injective
theorems in $H_v$-modules. We determine equivalent conditions for
split sequences in $H_v$-modules and present some related
results.
