Some combinatorial aspects of S^1 fixed points of Peterson varieties

, 2017
In this paper we investigate the partial order set An of S 1 fixed points of the Peterson variety Petn, a special subset of involutions of symmetric group Sn. The order is induced by the Bruhat order of Sn.

Toric deformation of the Hankel variety

, 2016
A combinatorial criterium for detecting the normality of the semigroup under the toric deformation (initial algebra of the coordinate ring) of the Hankel projective variety is studied and applied.

Mini-Workshop: PBW Structures in Representation Theory

, 2016
The PBW structures play a very important role in the Lie theory and in the theory of algebraic groups. The importance is due to the huge number of possible applications.

On Grassmann secant extremal varieties

, 2008
— In this paper we give a sharp lower bound on the dimension of Grassmann secant varieties of a given variety and we classify varieties for which the bound is attained.

Finite rank vector bundles on inductive limits of grassmannians

, 2002
If P 1 is the projective ind-space, i.e. P 1 is the inductive limit of linear embeddings of complex projective spaces, the Barth-Van de Ven-Tyurin (BVT) Theorem claims that every finite rank vector bundle on P 1 is isomorphic to a direct sum of line ...

Arakelov theory of the Lagrangian Grassmannian

, 1999
Let E be a symplectic vector space of dimension 2n (with the standard antidiagonal symplectic form) and let G be the Lagrangian Grassmannian over SpecZ, parametrizing Lagrangian subspaces in E over any base field.

Decomposable Skew-Symmetric Functions

, 2003
A skew-symmetric function F in several variables is said to be decomposable if it can be represented as a determinant det(fi(xj)) where fi are univariate functions. We give a criterion of the decomposability in terms of a Plücker-type identity imposed on
