The irreducibility of certain pure-cycle Hurwitz spaces
Fu Liu, Brian Osserman
We study "pure-cycle" Hurwitz spaces, parametrizing covers of the projective line having only one ramified point over each branch point. We start with the case of genus-0 covers, u…

Flatness of the linked Grassmannian
David Helm, Brian Osserman
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 Co…

Linked Grassmannians and crude limit linear series
Brian Osserman
In math.AG/0407496, a new construction of limit linear series is presented which functorializes and compactifies the original construction of Eisenbud and Harris, using a new space…
