18 p, 221.0 KB Intersection Pairing and intersection motive of surfaces / Wildeshaus, Jörg ; Centre de Recerca Matemàtica
We construct the Chow motive modelling intersection co-homology of a proper surface. We then study its functoriality properties. Using Murre's decompositions of the motive of a desingularization into KÄunneth components [Mr1], we show that such decompositions exist also for the intersection motive.

39 p, 337.3 KB Pure motives, mixed motives and extensions of motives associated to singular surfaces / Wildeshaus, Jörg ; Centre de Recerca Matemàtica
We first recall the construction of the Chow motive modelling intersection cohomology of a proper surface X and study its fundamental properties. Using Voevodsky's category of effective geometrical motives, we then study the motive of the exceptional divisor D in a non-singular blow-up of X. [...]
