FILTRATIONS OF THE PERVERSE SHEAF OF NEARBY CYCLES IN THE SEMI STABLE SITUATION by

Résumé

In the strict semi stable reduction situation, we describe the various filtrations of the perverse sheaf of nearby cycles coming from the stratification of the special fiber and determine which extensions given by these filtrations, are split or not. Considering the similarity with the results with my paper at Duke Math. J., it could be a good introduction before reading loc. cit.
