Naive liftings of dg modules

Abstract: The naive lifting for dg modules is the new concept introduced by M.Ono, S.Nasseh and myself for the purpose of unifying the ideas of lifting and weak lifting for modules over commutative rings. In this talk I will show how we get the obstruction class of naive liftings, which in fact coincides with the Atiyah class that has been introduced by Buchweitz-Flenner. This is a joint work with Saeed Nasseh and Maiko Ono.
