Multiple derived Lagrangian intersections

Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review


We give a new way to produce examples of Lagrangians in shifted symplectic derived stacks, based on multiple intersections. Specifically, we show that an m-fold homotopy fiber product of Lagrangians in a shifted symplectic derived stack is itself Lagrangian in a certain cyclic product of pairwise homotopy fiber products of the Lagrangians.
