Range characterization of the cosine transform on higher Grassmannians
Abstract
We characterize the range of the cosine transform on real Grassmannians in terms of the decomposition under the action of the special orthogonal group SO(n). Also a geometric interpretation of its image is given. The non- Archimedean analogues are discussed.
