Résumé: 

Intersection homology was introduced by Goresky-MacPherson in order to recover the Poincaré Duality in the context of pseudomanifolds.
In this talk we treat the following items:

  • How Goresky-MacPherson solved the problem? Perverse degree
  • Singular intersection homology. Poincaré Duality.
  • Cohomology/homology duality.
