Let X be an orthogonal Grassmannian parametrizing isotropic
subspaces in an even dimensional vector space equipped with a nondegenerate
symmetric form. We prove a Giambelli formula which expresses a...

Let V be a vector space with a nondegenerate symmetric form and
OG be the orthogonal Grassmannian which parametrizes maximal isotropic
subspaces in V . We give a presentation for the (small) quantum...
We study the Arakelov intersection ring of the arithmetic scheme
OG which parametrizes maximal isotropic subspaces in an even dimensional
vector space, equipped with the standard hyperbolic quadrati...
