AbstractThe perverse (Leray) filtration captures key topological information of algebraic maps. Recent studies of integrable systems (e.g. Hitchin system, Beauville-Mukai system) suggests two common features of the perverse filtration of abelian fibrations:1) the perverse filtration is multiplicative with respect to the cup product;2) the perversity of tautological classes is governed by the Ch...
