The trace conjecture for perverse schobers
The trace conjecture for perverse schobers
Let be an algebraic variety or stack, and let be a conic Lagrangian. Write for the loop space, and let be the Lagrangian determined by . The categorical trace of the 2-category of perverse schobers on with singular support in should be equivalent, as an -category, to the category of sheaves on with singular support in :
This conjecture proposes an A-model description of the categorical trace of perverse schobers, motivated by 3-dimensional mirror symmetry and the expected relationship between symplectic and coherent 2-categories. The Lagrangian is only approached or constructed in special cases, so the conjecture remains open.
