This conjecture has been settled by M. Saito via the theory of mixed Hodge modules and has various applications in the investigation of Albanese maps. Our technique is L^2 theoretic which gives concrete ...

The monodromy representation for any is semisimple. Remark 9 is NOT true for the Hopf fibration as one can check directly. It is a real algebraic proper submersion, but not holomorphic.
WebMar 13, 2013 · A cosheaf version of the i'th derived pushforward of the constant sheaf along a definable map is constructed directly as a representation of this category. We go on to clarify the relationship of cellular sheaves to cosheaves by providing a formula that defines a derived equivalence, which in turn recovers Verdier duality.
