Wild ramification determines the characteristic cycle

Name: Work Video:
Duration: 3 min 30 s
Description: Constructible complexes have the same characteristic cycle if they have the same wild ramification, even if the characteristics of the coefficients fields are different.Definition 1.2 ([B, 1.3]).Let X be a smooth scheme over a field k and let Λ be a finite field of characteristic ℓ invertible in k.Let F be a constructible complex of Λ-modules on X.
