Abstract
We classify rigid Schubert classes in orthogonal Grassmannians. More generally, given a representative of a Schubert class in an orthogonal Grassmannian, we give combinatorial conditions which guarantee that every linear space parametrized by meets a fixed linear space in the required dimension.
