摘要:Following the work of Calaque, Pantev, Toen, Vaquie and Vezzosi, we show that the moduli stack of bounded complexes of vector bundles on a smooth projective Calabi-Yau d-fold admits a (1-d) shifted Poisson structure by establishing a Lagrangian correspondence in the product of moduli stack of graded vector bundles and perfect complexes thereof. In the d=1 case, our theorem leads to a classification of the symplectic leaves of the regular part of the matrix algebra over the field of meromorphic functions on a complex elliptic curve. This is a joint work with Alexander Polishchuk.
