ON A THEOREM OF BRADEN

  • V. DRINFELD
  • D. GAITSGORY
Article

Abstract

We give a new proof of Braden’s theorem ([Br]) about hyperbolic restrictions of constructible sheaves/D-modules. The main geometric ingredient in the proof is a 1-parameter family that degenerates a given scheme Z equipped with a \( {\mathbb G} \) m -action to the product of the attractor and repeller loci.
