DESCRIPTION:[b]Speaker: Merlin Christ [/b] (Institut de mathématiques de J
 ussieu – Paris Rive Gauche) [nl][nl]\n[b]Abstract:[/b][nl]\nA complex of 
 stable infinity-categories is a categorification of a chain complex\, mea
 ning a sequence of stable infinity-categories together with a differentia
 l that squares to the zero functor. To produce examples of such categoric
 al complexes we introduce a categorification of the totalization construc
 tion\, which produces a categorical complex from a categorical multi-comp
 lex\, such as a commuting cube of stable infinity-categories. We will the
 n explain how categorified perverse sheaves\, also known as perverse scho
 bers\, on C^n (with a certain stratification) can be described in terms o
 f categorical cubes and categorical complexes of spherical functors. We w
 ill also see what categorical totalization means in this case geometrical
 ly. This talk is based on joint work with T. Dyckerhoff and T. Walde.\n[n
