Classical Yang-Baxter equations and Nijenhuis operators for Lie algebras (2502.18717v2)
Published 26 Feb 2025 in math.RA
Abstract: In this paper the conditions that when a Lie algebra is Nijenhuis are investigated. Furthermore all the Nijenhuis operators on $\mathfrak{sl}_2$ under the standard Cartan-Weyl basis are given. On the other hand, the notion of classical $P$-Nijenhuis Yang-Baxter equations is introduced by means of the bialgebraic theory for Nijenhuis Lie algebras.
