Homogeneous Rota–Baxter operators on the 3-Lie algebra (II)
Volume 149 / 2017
Abstract
We study k-order homogeneous Rota–Baxter operators of weight 1 on the simple 3-Lie algebra A_{\omega } (over a field \mathbb F of characteristic zero), which is realized by an associative commutative algebra A equipped with a derivation \varDelta and an involution \omega (Lemma 2.3). A k-order homogeneous Rota–Baxter operator on A_{\omega }, where k\in \mathbb Z, is a Rota–Baxter operator R satisfying R(L_m)=f(m+k)L_{m+k} for all generators \{ L_m \mid m\in \mathbb Z \} of A_{\omega } and a map f : \mathbb Z \rightarrow \mathbb F. We prove that R is a k-order homogeneous Rota–Baxter operator on A_{\omega } of weight 1 with k\not =0 if and only if R=0 (Theorem 3.2), and R is a 0-order homogeneous Rota–Baxter operator on A_{\omega } of weight 1 if and only if R is one of the thirty-eight possibilities which are described in Theorems 3.5, 3.7, 3.9, 3.10, 3.18, 3.21 and 3.22.
