Laurent Series and Asymptotic Behavior of Ext over Graded Complete Intersections


Let R be a graded commutative ring generated over a field by finitely many
homogeneous elements of positive degree. Work of Avramov, Buchweitz and Sally shows
that, under certain assumptions, the Laurent series expansions around 1 of the Hilbert series
of two graded R-modules and those of some of their Ext modules are related. When R is a
complete intersection, we show that such relations are connected to the asymptotic behavior
of the Ext modules. (This is joint work with David A. Jorgensen and Peder Thompson.)
