Abstract
In this paper, we introduce the cohomology of Rota-Baxter operators on Lie superalgebras. We define the cohomology of a Rota-Baxter operator R as the Chevalley Eilenberg cohomology of a certain Lie superalgebra induced by R with coefficients in a suitable representation. Then, we give the classification of the homogeneous Rota-Baxter operators of weight 0 on the Witt superalgebras. To apply our approach, we construct pre-Lie superalgebras from the homogeneous Rota-Baxter operators of weight 0 and their subadjacent Lie superalgebras.(c) 2022 Elsevier B.V. All rights reserved.
