Cycles on Algebraic Varieties [PDF]

Nagoya Mathematical Journal, 1955
In the present note, applying the theory of harmonic integrals, we shall show some results on cycles on algebraic varieties and give a new birational invariant.

Regular Tree Algebras [PDF]

Logical Methods in Computer Science, 2020
We introduce a class of algebras that can be used as recognisers for regular tree languages. We show that it is the only such class that forms a pseudo-variety and we prove the existence of syntactic algebras.

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 ...

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 ...

Algebraic Legendrian varieties [PDF]

Dissertationes Mathematicae, 2009
Real Legendrian subvarieties are classical objects of differential geometry and classical mechanics and they have been studied since antiquity. However, complex Legendrian subvarieties are much more rigid and have more exceptional properties. The most remarkable case is the Legendrian subvarieties of projective space and prior to the author's research ...

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.

Interior Algebras and Varieties

Journal of Algebra, 1999
The authors consider rings and semigroups with an additional unary operation which mimics the operation of taking the interior of a subset in topological spaces. More precisely, they call a ring or semigroup \(R\) an interior algebra if \(R\) is equipped with a unary operation \(a\mapsto I(a)\) such that \(I(a)I(b)=I(b)I(a)\), \(aI(a)=I(a)\), \(I(I(a))=

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 ...
