چکیده
Abstract We show that if X n {X_{n}} is a variety of c × {c\times n} -matrices stable under the group Sym ( stretchy="false">[ stretchy="false">] stretchy="false">) {\operatorname{Sym}([n])} column permutations and forgetting last maps into - 1 {X_{n-1}} , then number -orbits on irreducible components quasipolynomial in n for all sufficiently large . To this end, we introduce category affine

Embeddings of Symmetric Varieties
We generalize to the case of a symmetric variety the construction of the enveloping semigroup of a semisimple algebraic group due to E.B. Vinberg, and we establish a connection with the wonderful completion of the associated adjoint symmetric variety due to C. De Concini and C.
متن کاملSYMMETRIC k - VARIETIES
Let G be a connected reductive algebraic group defined over a field k of characteristic not 2, θ an involution of G defined over k, H a k-open subgroup of the fixed point group of θ and Gk (resp. Hk) the set of k-rational points of G (resp. H). The variety Gk/Hk is called a symmetric k-variety. For k = R and C the representation theory of these varieties has been studied extensively. To study t...
متن کاملAN ALGORITHM FOR FINDING THE EIGENPAIRS OF A SYMMETRIC MATRIX
The purpose of this paper is to show that ideas and techniques of the homotopy continuation method can be used to find the complete set of eigenpairs of a symmetric matrix. The homotopy defined by Chow, Mallet- Paret and York [I] may be used to solve this problem with 2""-n curves diverging to infinity which for large n causes a great inefficiency. M. Chu 121 introduced a homotopy equation...
متن کاملIrreducible components of characteristic varieties
We give a dimension bound on the irreducible components of the characteristic variety of a system of linear partial di.erential equations de0ned from a suitable 0ltration of the Weyl algebra An. This generalizes an important consequence of the fact that a characteristic variety de0ned from the order 0ltration is involutive. More explicitly, we consider a 0ltration of An induced by any vector (u...
متن کاملFundamental Group of Locally Symmetric Varieties
The geometry of moduli spaces of complex abelian varieties and of compactifications of those moduli spaces has been the object of much study in the last few years. Given such a compactified moduli space it is natural to ask about the fundamental group of a resolution of singularities. This problem has been studied in some special cases, for instance in [K], [HK] and [HS]. It follows from the re...
