Abstract
We study direct sum decompositions of pure projective torsion free modules over one-dimensional commutative noetherian domains. Drawing inspiration from the representation theory of orders in separable algebras, we study when every pure projective torsion free module is a direct sum of finitely generated modules.
A satisfactory criterion is given for analytically unramified reduced local rings and for Bass domains.
