The Prism tableau model for Schubert polynomials [PDF]

, 2015
The Schubert polynomials lift the Schur basis of symmetric polynomials into a basis for Z[x1,x2,...]. We suggest the "prism tableau model" for these polynomials.

Equivariant quantum Schubert polynomials

Advances in Mathematics, 2014
We establish an equivariant quantum Giambelli formula for partial flag varieties. The answer is given in terms of a specialization of universal double Schubert polynomials. Along the way, we give new proofs of the presentation of the equivariant quantum cohomology ring, as well as Graham-positivity of the structure constants in equivariant quantum ...

Morphophysiological and Productive Responses of Forage Cactus Clones to the Water and Nutrient Use in the Brazilian Semi‐Arid Region

Grass and Forage Science, Volume 80, Issue 4, December 2025.
ABSTRACT Crops adapted to semi‐arid conditions enhance forage supply amid water scarcity. This study aimed to compare six forage cactus clones (Orelha de Elefante Mexicana [OEM, Opuntia stricta (Haw.) Haw.]; Orelha de Elefante Africana [OEA, Opuntia undulata Griffiths]; V19, Opuntia larreyi F.A.C.

Schubert Polynomials and the Nilcoxeter Algebra

Advances in Mathematics, 1994
Schubert polynomials \({\mathfrak S}_ \sigma(x_ 1,x_ 2,\dots)\) indexed by permutations have been introduced and investigated by \textit{I. N. Bernstein}, \textit{I. M. Gel'fand} and \textit{S. I. Gel'fand} [Russ. Math. Surveys 28, No. 3, 1-26 (1973; Zbl 0286.57025)], \textit{M. Demazure} [Ann. Sci. École Norm. Sup., IV. Sér.

Polarization and Gorenstein liaison

Journal of the London Mathematical Society, Volume 112, Issue 6, December 2025.
Abstract A major open question in the theory of Gorenstein liaison is whether or not every arithmetically Cohen–Macaulay subscheme of Pn$\mathbb {P}^n$ can be G‐linked to a complete intersection. Migliore and Nagel showed that if such a scheme is generically Gorenstein (e.g., reduced), then, after re‐embedding so that it is viewed as a subscheme of Pn ...

A combinatorial proof that Schubert vs. Schur coefficients are nonnegative [PDF]

, 2014
We give a combinatorial proof that the product of a Schubert polynomial by a Schur polynomial is a nonnegative sum of Schubert polynomials. Our proof uses Assaf's theory of dual equivalence to show that a quasisymmetric function of Bergeron and Sottile ...

Employee Diversity and Environmental Innovation: The Roles of Gender, Nationality, and Education

Business Strategy and the Environment, Volume 34, Issue 7, Page 8725-8741, November 2025.
ABSTRACT This paper investigates the roles of employee diversity for environmental innovations in firms. Utilizing firm‐level survey data on environmental innovations and employer–employee register data, we construct measures of employee diversity across education, nationality, and gender for over 6500 Swedish firms.

Hearing a Feeling: Music Emotion Recognition and Callous‐Unemotional Traits in Early Childhood

Child Development, Volume 96, Issue 6, Page 2247-2256, November/December 2025.
ABSTRACT Music is a powerful medium to study emotion recognition. However, findings are mixed regarding the proficiency of young children to detect emotion conveyed by music. Moreover, we lack knowledge about music emotion recognition and callous‐unemotional traits, which portend risk for externalizing problems.

A presentation of the torus-equivariant quantum K-theory ring of flag manifolds of type A, Part II: quantum double Grothendieck polynomials

Forum of Mathematics, Sigma
In our previous paper, we gave a presentation of the torus-equivariant quantum K-theory ring $QK_{H}(Fl_{n+1})$ of the (full) flag manifold $Fl_{n+1}$ of type $A_{n}$ as a quotient of a polynomial ring by an explicit ideal.

Existence and orthogonality of stable envelopes for bow varieties

Bulletin of the London Mathematical Society, Volume 57, Issue 11, Page 3249-3306, November 2025.
Abstract Stable envelopes, introduced by Maulik and Okounkov, provide a family of bases for the equivariant cohomology of symplectic resolutions. They are part of a fascinating interplay between geometry, combinatorics and integrable systems. In this expository article, we give a self‐contained introduction to cohomological stable envelopes of type A$A$
