Rational smoothness and affine Schubert varieties of type A [PDF]

Discrete Mathematics & Theoretical Computer Science, 2011
The study of Schubert varieties in G/B has led to numerous advances in algebraic combinatorics and algebraic geometry. These varieties are indexed by elements of the corresponding Weyl group, an affine Weyl group, or one of their parabolic quotients ...

On equivariant Serre problem for principal bundles [PDF]

, 2018
Let $E_G$ be a $\Gamma$--equivariant algebraic principal $G$--bundle over a normal complex affine variety $X$ equipped with an action of $\Gamma$, where $G$ and $\Gamma$ are complex linear algebraic groups.

Hodge filtration on local cohomology, Du Bois complex and local cohomological dimension

Forum of Mathematics, Pi, 2022
We study the Hodge filtration on the local cohomology sheaves of a smooth complex algebraic variety along a closed subscheme Z in terms of log resolutions and derive applications regarding the local cohomological dimension, the Du Bois complex, local ...

Extension of Operational Matrix Technique for the Solution of Nonlinear System of Caputo Fractional Differential Equations Subjected to Integral Type Boundary Constrains

Entropy, 2021
We extend the operational matrices technique to design a spectral solution of nonlinear fractional differential equations (FDEs). The derivative is considered in the Caputo sense.

The EKOR-stratification on the Siegel modular variety with parahoric level structure [PDF]

Épijournal de Géométrie Algébrique
We study the arithmetic geometry of the reduction modulo $p$ of the Siegel modular variety with parahoric level structure. We realize the EKOR-stratification on this variety as the fibers of a smooth morphism into an algebraic stack parametrizing ...

Note on absolute sets of rigid local systems

Comptes Rendus. Mathématique, 2022
In this note we give a description up to a quasi-finite morphism of the absolute sets of simple cohomologically rigid local systems on a smooth complex quasi-projective algebraic variety.

A New Family of Boolean Functions with Good Cryptographic Properties

Axioms, 2021
In 2005, Philippe Guillot presented a new construction of Boolean functions using linear codes as an extension of the Maiorana–McFarland’s (MM) construction of bent functions.
