%0 Journal Article %T Rota-Baxter 3-Lie algebras %A Ruipu Bai %A Li Guo %A Jianqian Li %A Yong Wu %J Mathematics %D 2013 %I arXiv %R 10.1063/1.4808053. %X In this paper we introduce the concepts of a Rota-Baxter operator and a differential operator with weights on an $n$-algebra. We then focus on Rota-Baxter 3-Lie algebras and show that they can be derived from Rota-Baxter Lie algebras and pre-Lie algebras and from Rota-Baxter commutative associative algebras with derivations. We also establish the inheritance property of Rota-Baxter 3-Lie algebras. %U http://arxiv.org/abs/1306.1990v1
