dc.description.abstractengThis thesis consists of two parts: In the first, we develop the homotopy theory of differential graded operads over any unital commutative ring. The main idea is to consider the symmetric group actions as part of the operadic structure and not of the underlying category. We introduce a new dual category of higher cooperads, a new higher cobar-bar adjunction with the category of operads, and a new notion of higher homotopy operads for which we establish the homotopy properties. In the second part, we introduce a category of weak Lie 3-algebras with suitable weak morphisms. The definition is based on the construction of a partial resolution of the Koszul dual cooperad of the Lie operad with free symmetric group actions. Weak Lie 3-algebras and their morphisms are then defined as solutions to Maurer-Cartan equations. We prove a version of the homotopy transfer theorem for weak Lie 3-algebras and provide a skewsymmetrization construction from weak Lie 3-algebras to 3-term L-infinity algebras. Finally, we provide some initial applications of weak Lie 3-algebras in higher differential
