DESCRIPTION:Ai Guan\, Lancaster University\nKoszul duality is a phenomeno
 n appearing in many areas of mathematics\, such as rational homotopy theor
 y and deformation theory and representation theory. For differential grade
 d (dg) algebras\, it is often formulated as a Quillen equivalence between 
 model categories of augmented dg algebras and conilpotent dg coalgebras\, 
 and their corresponding dg modules and comodules. In this talk we consider
  what happens when the conilpotence condition is removed\; the result is a
 n exotic model structure on dg modules that is "of second kind"\, i.e. wea
 k equivalences are finer than quasi-isomorphisms. This is joint work with 
 Andrey Lazarev.
