Abstract

We give a linear algebraic construction of the Lafforgue spaces associated to the Grassmannians G(2,n)G(2,n) by blowing up certain explicitly defined monomial ideals, which sharpens and generalizes a result of Faltings. As an application, we provide a family of homogeneous varieties with high complexity and with nice compactifications, which exhibits the notion of homeward compactification introduced in our previous work in a non-spherical setting.
