Reduction of $L_{\infty }$-Algebras of Observables on Multisymplectic Manifolds

Casey Blacker, Antonio Michele Miti, Leonid Ryvkin

We develop a reduction scheme for the $L_{\infty }$-algebra of observables on a premultisymplectic manifold $(M,\omega )$ in the presence of a compatible Lie algebra action $\mathfrak{g}\cu…
