RT journal article T1 On the simple transposed Poisson algebras and Jordan superalgebras A1 Fernández Ouaridi, Amir A2 Matemáticas K1 Jordan superalgebra K1 Lie algebra K1 Poisson algebra K1 Transposed Poisson algebra AB We prove that a transposed Poisson algebra is simple if and only if its associated Lie bracket is simple. Consequently, any simple finite-dimensional transposed Poisson algebra over an algebraically closed field of characteristic zero is trivial. Similar results are obtained for transposed Poisson superalgebras. An example of a non-trivial simple finite-dimensional transposed Poisson algebra is constructed by studying the transposed Poisson structures on the modular Witt algebra. Furthermore, we show that the Kantor double of a transposed Poisson algebra is a Jordan superalgebra, that is, we prove that transposed Poisson algebras are Jordan brackets. Additionally, a simplicity criterion for the Kantor double of a transposed Poisson algebra is obtained. PB Academic Press Inc.
