Shifted symplectic higher Lie groupoids and classifying spaces

arXiv:2112.01417 · doi:0.1016/j.aim.2022.108829

Abstract

We introduce the concept of -shifted symplectic Lie -groupoids and symplectic Morita equivalences between them. We then build various models for the 2-shifted symplectic structure on the classifying stack in this setting and construct explicit symplectic Morita equivalences between them.
