On the interior motive of certain Shimura varieties : the case of Picard varieties
arXiv:1705.03235
Abstract
The aim of this article is the construction of the interior motive of a Picard variety. Those are Shimura varieties of PEL type. Our result is an application of the strategy developed by Wildeshaus to construct a Hecke-invariant motive whose realizations correspond to interior cohomology.
