요약 | By a fundamental theorem of Quillen, there is a natural duality - an instance of general Koszul duality - between differential graded (DG) Lie algebras and DG cocommutative coalgebras defined over a field $k$ of characteristic $0$. A cyclic pairing (i.e., an inner product satisfying a natural cyclicity condition) on the cocommutative coalgebra gives rise to an interesting structure on the universal enveloping algebra $\\mathcal{U}\\mathfrak{a}$ of the Koszul dual Lie algebra $\\mathfrak{a}$ called the derived Poisson bracket. We study the general properties of cyclic pairings on DG coalgebras and DG Lie coalgebras. We also study the derived Poisson brackets on universal enveloping algebras $\\mathcal{U}\\mathfrak{a}$, and their relation to the classical Poisson brackets on the derived moduli spaces $\\mathrm{DRep}_\\mathfrak{g}(\\mathfrak{a})$ of representations of $\\mathfrak{a}$ in a finite dimensional semisimple Lie algebra $\\mathfrak{g}$. More specifically, we show that certain derived character maps of $\\mathfrak{a}$ intertwine the derived Poisson bracket with the classical Poisson structure on the representation homology $\\mathrm{HR}_\\bullet(\\mathfrak{a},\\,\\mathfrak{g})$ related to $\\mathrm{DRep}_\\mathfrak{g}(\\mathfrak{a})$. |
