Demazure crystals and the energy function [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2011
There is a close connection between Demazure crystals and tensor products of Kirillov–Reshetikhin crystals. For example, certain Demazure crystals are isomorphic as classical crystals to tensor products of Kirillov–Reshetikhin crystals via a canonically ...

Stepwise Cooling Events in the Western Arctic at 8.2 and 4.2 ka: Proxy Development and Application

open access: yesPaleoceanography and Paleoclimatology, Volume 40, Issue 12, December 2025.
Abstract Hydroxylated glycerol dialkyl glycerol tetraether (GDGT)‐based proxies have recently been proposed for reconstructing sea surface temperatures (SSTs) in polar oceans, but their reliability has not yet been sufficiently validated. We investigated the spatial distribution of hydroxylated GDGTs in surface sediments from the western Arctic Ocean ...

A product formula for certain Littlewood-Richardson coefficients for Jack and Macdonald polynomials [PDF]

open access: yes, 2014
Jack polynomials generalize several classical families of symmetric polynomials, including Schur polynomials, and are further generalized by Macdonald polynomials.

Full decomposition of phenotypic variance in dichotomous traits: New methods and key implications for behaviour, demography and evolutionary ecology

open access: yesMethods in Ecology and Evolution, Volume 16, Issue 12, Page 2741-2759, December 2025.
Abstract Numerous traits that define behaviour, development, life‐history and species ecology are expressed as dichotomous alternative phenotypes (e.g. morphological and behavioural polyphenisms, reproductive vs. non‐reproductive states, movement vs. philopatry).

‘Left Behind Places’: Examining the Evolution of a Concept With an Application to the Canadian Regional Development Context

open access: yesGrowth and Change, Volume 56, Issue 4, December 2025.
ABSTRACT ‘Left‐behind places’ (LBPs) are generally defined as places experiencing economic stagnation and decline, typically reflected in post‐industrial regions and rural areas. In recent years, the concept has gained increased popularity within urban and regional studies in the United Kingdom (UK) and other European countries.

Wreath Macdonald operators

open access: yesForum of Mathematics, Sigma
We construct a novel family of difference-permutation operators and prove that they are diagonalized by the wreath Macdonald P-polynomials; the eigenvalues are written in terms of elementary symmetric polynomials of arbitrary degree.

Macdonald polynomials for super-partitions

open access: diamondPhysics Letters B
We introduce generalization of famous Macdonald polynomials for the case of super-Young diagrams that contain half-boxes on the equal footing with full boxes. These super-Macdonald polynomials are polynomials of extended set of variables: usual $p_k$ variables are accompanied by anti-commuting Grassmann variables $θ_k$.

Narrow, Open Canopy Architecture Enables More Effective Management of Mango Scale, Aulacaspis tubercularis Newstead in Mango Orchards

open access: yesJournal of Applied Entomology, Volume 149, Issue 10, Page 1532-1541, December 2025.
ABSTRACT Pest management in horticultural crops must become more efficient, capitalising on non‐chemical means of pest reduction. In mango (Mangifera Indica), the development of highly productive orchard and canopy management systems offers a potential means to reduce pressure and damage from economically important pests such as mango scale (Aulacaspis

Rodrigues Formulas for the Macdonald Polynomials

open access: yesAdvances in Mathematics, 1997
We present formulas of Rodrigues type giving the Macdonald polynomials for arbitrary partitions through the repeated application of creation operators on the constant 1. Three expressions for the creation operators are derived one from the other.
