Joint IAS/PU Arithmetic Geometry
Inertia Stacks, Gerbes and Intersection Cohomology
I will discuss a theorem obtained in joint work with Wyss and Ziegler, which is devoted to describing the Frobenius traces for the IC sheaf on moduli space of objects in symmetric abelian categories linear over a finite field. The formula is expressed with the help of inertia stacks and natural obstruction gerbes on moduli stacks.
