Degrees of real Grassmann varieties
For integers m ≥ p ≥ 2, let GR = GR(m,m + p) ⊂ RP N be the Plücker embedding of the Grassmannian of m-subspaces in Rm+p . We consider a central projection of GR into a projective space RP mp of the same dimension as GR . Although GR may be non-orientable, the topological degree of this projection can be properly defined. Its values are unsigned integers. It turns out that when mp is even, the d...
متن کاملWitt Groups of Grassmann Varieties
We compute the total Witt groups of (split) Grassmann varieties, over any regular base X. The answer is a free module over the total Witt ring of X. We provide an explicit basis for this free module, which is indexed by a special class of Young diagrams, that we call even Young diagrams.
متن کاملDifferential Operators on Grassmann Varieties
Following Weyl’s account in The Classical Groups we develop an analogue of the (first and second) Fundamental Theorems of Invariant Theory for rings of differential operators: when V is a k-dimensional complex vector space with the standard SLkC action, we give a presentation of the ring of invariant differential operators D(C[V n])SLkC and a description of the ring of differential operators on...
متن کاملSchubert unions in Grassmann varieties
We study subsets of Grassmann varieties G(l, m) over a field F , such that these subsets are unions of Schubert cycles, with respect to a fixed flag. We study the linear spans of, and in case of positive characteristic, the number of Fq-rational points on such unions. Moreover we study a geometric duality of such unions, and give a combinatorial interpretation of this duality. We discuss the ma...
متن کاملDecomposable subspaces, linear sections of Grassmann varieties, and higher weights of Grassmann codes
Given a homogeneous component of an exterior algebra, we characterize those subspaces in which every nonzero element is decomposable. In geometric terms, this corresponds to characterizing the projective linear subvarieties of the Grassmann variety with its Plücker embedding. When the base field is finite, we consider the more general question of determining the maximum number of points on sect...
