Intersection pairing and intersection motive of surfaces, by J. Wildeshaus

We construct the Chow motive modelling intersection cohomology of a proper surface. We then study its functoriality properties. Using Murre's decompositions of the motive of a desingularization into Kuenneth components, we show that such decompositions exist also for the intersection motive.
