Location: Room 35, House 5, Kräftriket, Department of Mathematics, Stockholm University

Respondent: Ville Nordström

Supervisor: Alexander Berglund

Abstract: In this thesis we study formal differential graded algebras and coalgebras. As our tools we use theory of Koszul algebras and some homotopical algebra. We also give some examples of Koszul algebras, formal differential graded algebras and non-formal differential graded algebras from algebraic topology.
