Intermediate extension of Chow motives of Abelian type

Jörg Wildeshaus

Published 2012-11-22, updated 2016-09-23Version 3

In this article, we give an unconditional construction of a motivic analogue of the intermediate extension in the context of Chow motives of Abelian type. Our main application concerns intermediate extensions of Chow motives associated to Kuga families to the Baily--Borel compactification of a Shimura variety.
