The $L_\infty$-algebra of a symplectic manifold

Bas Janssens, Leonid Ryvkin and Cornelia Vizman

Vol. 314 (2021), No. 1, 81–98

We construct an L-algebra on the truncated canonical homology complex of a symplectic manifold, which naturally projects to the universal central extension of the Lie algebra of Hamiltonian vector fields.
