Lecture notes on the symplectic geometry of graded manifolds and higher Lie groupoids
These notes study symplectic structures on graded manifolds and their global counterparts, higher Lie groupoids. They start with graded manifolds, then symplectic Q manifolds and Lagrangian Q submanifolds, and then the shifted symplectic structure on higher Lie groupoids.
