The decomposition theorem, perverse sheaves and the topology of algebraic maps
M de Cataldo, L Migliorini - Bulletin of the American Mathematical Society, 2009 - ams.org
We give a motivated introduction to the theory of perverse sheaves, culminating in the
decomposition theorem of Beilinson, Bernstein, Deligne and Gabber. A goal of this survey is …
