Homogeneous Rota-Baxter operators on $A_{\omega }$ (II)

Abstract

In this paper we study $k$-order homogeneous Rota-Baxter operators with weight $1$ on the simple $3$-Lie algebra $A_{\omega }$ (over a field of characteristic zero), which is realized by an associative commutative algebra $A$ and a derivation $\Delta$ and an involution $\omega$ (Lemma \mref{lem:rbd3}). A $k$-order homogeneous Rota-Baxter operator on $A_{\omega }$ is a linear map $R$ satisfying $R(L_m)=f(m+k)L_{m+k}$ for all generators $\{L_m|m\in \mathbb{Z}\}$ of $A_{\omega }$ and a map $f:\mathbb{Z}\to \mathbb{F}$, where $k\in \mathbb{Z}$. We prove that $R$ is a $k$-order homogeneous Rota-Baxter operator on $A_{\omega }$ of weight $1$ with $k\ne 0$ if and only if $R=0$ (see Theorems 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 forty possibilities which are described in Theorems3.5, 3.7, 3.9, 3.10, 3.18, 3.21 and 3.22.
