Singularities of Affine Schubert Varieties [PDF]

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2009
This paper studies the singularities of affine Schubert varieties in the affine Grassmannian (of type A_l^{(1)}). For two classes of affine Schubert varieties, we determine the singular loci; and for one class, we also determine explicitly the tangent ...

Which Schubert varieties are local complete intersections? [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2012
We characterize by pattern avoidance the Schubert varieties for $\mathrm{GL}_n$ which are local complete intersections (lci). For those Schubert varieties which are local complete intersections, we give an explicit minimal set of equations cutting out ...

Combinatorial description of the cohomology of the affine flag variety [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2020
We construct the affine version of the Fomin-Kirillov algebra, called the affine FK algebra, to investigatethe combinatorics of affine Schubert calculus for typeA. We introduce Murnaghan-Nakayama elements and Dunklelements in the affine FK algebra.

Kraśkiewicz-Pragacz modules and some positivity properties of Schubert polynomials [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2015
We use the modules introduced by Kraśkiewicz and Pragacz (1987, 2004) to show some positivity propertiesof Schubert polynomials. We give a new proof to the classical fact that the product of two Schubert polynomialsis Schubert-positive, and also show a ...

Electromagnetic Field Enhancement of Nanostructured TiN Electrodes Probed with Surface-Enhanced Raman Spectroscopy

open access: yesSensors, 2022
We present a facile approach for the determination of the electromagnetic field enhancement of nanostructured TiN electrodes. As model system, TiN with partially collapsed nanotube structure obtained from nitridation of TiO2 nanotube arrays was used ...
