Flatness of the linked Grassmannian

David Helm, Brian Osserman

Published 2006-05-15Version 1

We show that the linked Grassmannian scheme, which arises in a functorial compactification of spaces of limit linear series, and in local models of certain Shimura varieties, is Cohen-Macaulay, reduced, and flat. We give an application to spaces of limit linear series.
