Abstract

In the paper we study homogeneous Rota-Baxter operators with weight zero on the infinite dimensional simple $3$-Lie algebra $A_{\omega}$ over a field $F$ ( $ch F=0$ ) which is realized by an associative commutative algebra $A$ and a derivation $\Delta$ and an involution $\omega$ ( Lemma \mref{lem:rbd3} ). A homogeneous Rota-Baxter operator on $A_{\omega}$ is a linear map $R$ of $A_{\omega}$ satisfying $R(L_m)=f(m)L_m$ for all generators of $A_{\omega}$, where $f : A_{\omega} \rightarrow F$. We proved that $R$ is a homogeneous Rota-Baxter operator on $A_{\omega}$ if and only if $R$ is the one of the five possibilities $R_{0_1}$, $R_{0_2}$,$R_{0_3}$,$R_{0_4}$ and $R_{0_5}$, which are described in Theorem \mref{thm:thm1}, \mref{thm:thm4}, \mref{thm:thm01}, \mref{thm:thm03} and \mref{thm:thm04}. By the five homogeneous Rota-Baxter operators $R_{0_i}$, we construct new $3$-Lie algebras $(A, [ , , ]_i)$ for $1\leq i\leq 5$, such that $R_{0_i}$ is the homogeneous Rota-Baxter operator on $3$-Lie algebra $(A, [ , , ]_i)$, respectively.
