Abstract
For a left noetherian ring Λ,we establish a bijective corre- spondence between equivalence classes of cotilting Λ-modules which are not necessarily finitely generated,and torsion pairs (T , F ) for the category of finitely generated Λ-modules with Λ ∈F. In the second part of this paper,we give a complete classification of all cotilting modules over a tame hereditary artin algebra.Keywords
