报告摘要:Deformation theory of algebraic structures originates from Gerstenhaber’s pioneering work in 1963. Differential graded Lie algebras, or L-infty-algebras in gereral, play crucial roles in deformation theory. In this talk, we will introduce a cohomology theory for Rota-Baxter algebras of any weight. And we will see that lower degree cohomology groups control the formal deformations of Rota-Baxter algebras . We make explicit the L-infty-algebra structure over the cochain complex defining cohomology groups and introduce the notion of homotopy Rota-Baxter algebras as Maurer-Cartan elements of this L-infty-algebra.
