报告摘要:
Minimal models of algebras originated from rational homotopy theory and play an important role in algebra. For algebraic structures, it is also important to seek minimal models, say, homotopy version of them. For instance, A- infinity algebras are the homotopy version of associative algebras, which can be obtained by Koszul duality. However, for operated algebras such Rota-Baxter algebras or differential algebras with nonzero weights, the minimal models remained open. Recently we found a method to produce minimal models for such operated algebras. This talk is a survey about recent work on this subject.
