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.
