The wreath product construction for Jordan superalgebras and Poisson superalgebras

About 8 years old · traced to

Let J1J_1 be a Jordan superalgebra with product ∘\circ, let D:J1→J1D:J_1\to J_1 be an odd superderivative such that D2=0D^2=0, and let HH be a Poisson superalgebra with products ( {  })(\,\{\,\ \}). Define J=H⊗J1J=H\otimes J_1 with the product

(a⊗x)∙(b⊗y)=ab⊗(x∘y)+{a,b}⊗D(x)∘D(y)(a\otimes x)\bullet(b\otimes y)=ab\otimes(x\circ y)+\{a,b\}\otimes D(x)\circ D(y)

Wreath product conjecture. The algebra JJ is a Jordan superalgebra. In this case, JJ should be called the wreath product of J1J_1 with HH.

This proposes a wreath-product construction combining a Jordan superalgebra with a Poisson superalgebra, analogous to wreath products for groups, Lie algebras, and associative algebras. The supplied text presents the assertion as a question and gives no resolution.
