Abstract

Transposed Poisson algebra was introduced as a dual notion of the Poisson algebra by switching the roles played by the commutative associative operation and Lie operation in the Leibniz rule defining the Poisson algebra. Let HH be a Hopf algebra with a bijective antipode and AA an HH-comodule transposed Poisson algebra. Assume that there exists an HH-colinear map which is also an algebra map from HH to the transposed Poisson center of AA. In this paper we generalize the fundamental theorem of (A,H)(A, H)-Hopf modules to transposed Poisson (A,H)(A, H)-Hopf modules and deduce relative projectivity in the category of transposed Poisson (A,H)(A, H)-Hopf modules.
