Title：An introduction to algebraic deformation theory
Abstract: This talk is an informal and elementary introduction to algebraic deformation theory. In the first part, we study deformations and homotopy theory of associative algebras following the original approch of Gerstenhaber and introduce A-infinity algebras à la Stasheff, and we explain the framework of Koszul duality of operad to justify these results. In the second part, we explain our recent work on deformations and homotopy theory of Rota-Baxter type structures orginated from the Yang-Baxter equation.
