Flag Gromov-Witten invariants via crystals [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2014
We apply ideas from crystal theory to affine Schubert calculus and flag Gromov-Witten invariants. By defining operators on certain decompositions of elements in the type-$A$ affine Weyl group, we produce a crystal reflecting the internal structure of ...

Cohomology classes of rank varieties and a counterexample to a conjecture of Liu [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2015
To each finite subset of a discrete grid $\mathbb{N}×\mathbb{N}$ (a diagram), one can associate a subvariety of a complex Grassmannian (a diagram variety), and a representation of a symmetric group (a Specht module).

LS algebras, valuations, and Schubert varieties

open access: yesRendiconti Lincei, Matematica e Applicazioni, 2023
In this paper, we propose an algebraic approach via Lakshmibai–Seshadri (LS) algebras to establish a link between standard monomial theories, Newton–Okounkov bodies and valuations. This is applied to Schubert varieties, where this approach is compatible with the one using Seshadri stratifications in arXiv:2112.03776, showing that LS paths encode ...

Governing singularities of Schubert varieties

open access: yesJournal of Algebra, 2008
We present a combinatorial and computational commutative algebra methodology for studying singularities of Schubert varieties of flag manifolds. We define the combinatorial notion of *interval pattern avoidance*. For "reasonable" invariants P of singularities, we geometrically prove that this governs (1) the P-locus of a Schubert variety, and (2) which

Cycle Intersection for SOp,q-Flag Domains

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2020

Sometimes Hot, Sometimes Not: The Relations Between Selected Situational Vocational Interests and Situation Perception

open access: yesEuropean Journal of Personality, EarlyView., 2020
Abstract Vocational interests are traditionally conceived as stable preferences for different activities. However, recent theorizing suggests their intraindividual variability. This preregistered experience sampling study examined intraindividual variation in selected vocational interests states and related situation and person factors (N = 237 ...

Kazhdan-Lusztig polynomials of boolean elements [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2013
We give closed combinatorial product formulas for Kazhdan–Lusztig poynomials and their parabolic analogue of type $q$ in the case of boolean elements, introduced in [M. Marietti, Boolean elements in Kazhdan–Lusztig theory, J.
