Title: Perspectives on the stable cohomology of compactifications of A_g
Abstract: By classical work of Borel, it is well known that the rational
cohomology of the moduli space A_g of principally polarized abelian
varieties of dimension g stabilizes in degree k<g, In this talk, I would
like to review stability results on compactifications of A_g, such as
the Satake compactification and toroidal compactifications.
