WebAug 1, 2024 · Intuitively, a derived symplectic form is therefore a non-degenerate map T Y ∧ T Y → O Y [n] which is B G a-equivariant (i.e. it lifts to HC 2 − n − (Y), and this is a datum 3). Remark 4.7. If Y is a (quasi-smooth) derived Deligne-Mumford stack and ω ∈ HC 3 − (Y) is a (− 1) derived symplectic structure on Y, let us http://www.math.polytechnique.fr/cmat/viterbo/Eilenberg/Eilenberg.pdf
