Pieri rule for the affine flag variety [PDF]

Advances in Mathematics, 2015
We prove the affine Pieri rule for the cohomology of the affine flag variety conjectured by Lam, Lapointe, Morse and Shimozono. We study the cap operator on the affine nilHecke ring that is motivated by Kostant and Kumar’s work on the equivariant cohomology of the affine flag variety. We show that the cap operators for Pieri elements are the same as

A reciprocity law and the skew Pieri rule for the symplectic group [PDF]

Journal of Mathematical Physics, 2017
We use the theory of skew duality to show that decomposing the tensor product of k irreducible representations of the symplectic group Sp2m=Sp2m(ℂ) is equivalent to branching from Sp2n to Sp2n1×⋯×Sp2nk, where n,n1,…,nk are positive integers such that n=n1+⋯+nk and the njs depend on m as well as the representations in the tensor product.

Drought and Herbivory Have Selective Transgenerational Effects on Soybean Eco‐Physiology, Defence and Fitness

Plant, Cell &Environment, Volume 49, Issue 7, Page 4352-4371, July 2026.
ABSTRACT Soybeans, one of the most important legumes, face multiple stresses including drought and herbivory. But the potential transfer of the interactive effects of these stressors onto the transgenerational plants has not been understood. We hypothesised that progeny from stressed parents will have enhanced ecophysiology and defence traits through ...

Anthraquinones From Epicoccum sp., a Fungus Isolated From Gut of Dione juno That Feeds on Passifloras

Chemistry &Biodiversity, Volume 23, Issue 6, June 2026.
An Epicoccum fungus was isolated from gut of larvae of the butterfly Dione juno juno that feeds intensively on leaves of Passifloras. This fungus produces hydroxyanthraquinones that moderately inhibits growth of some Bacillus that coexist with the fungus in the insect gut, suggesting that it is probably important for microbial embalance in gut flora ...

Photobiomodulation Alleviates Insulin Resistance Induced by Intermittent Hypoxia, Through Preservation of Adipose Tissue Insulin Signaling and Reduction of Hepatic Oxidative Stress in Mice

Comprehensive Physiology, Volume 16, Issue 3, June 2026.
Photobiomodulation (PBM), through its organ‐specific action, exerts beneficial effects on metabolic complications induced by intermittent hypoxia (IH), making it a promising therapeutic strategy for preventing IH‐induced insulin resistance. Graphical abstract created from illustrations provided by BioRender.

Comparative Analysis of Lepidopteran Community Structure Using DNA Metabarcoding: Warm‐Temperate Forest Versus Grass‐Shrub Ecotones in Pangquangou National Nature Reserve

Ecology and Evolution, Volume 16, Issue 6, June 2026.
This study confirms that the method based on DNA metabarcoding qualifies as a cost‐efficient alternative to traditional approaches, as well as a better understanding for future assessment of insect diversity. ABSTRACT Lepidoptera is a widely geographically distributed insect order that plays crucial ecological roles in forest and grass‐shrub ecosystems

A geometric proof of an equivariant Pieri rule for flag manifolds [PDF]

Forum Mathematicum, 2019
Abstract We use geometry to give a short proof of an equivariant Pieri rule in the classical flag manifold. This rule is due to Robinson, who gave an algebraic proof.

Inkjet‐Printed Physical Unclonable Functions For Secure Authentication

Small, Volume 22, Issue 33, 12 June 2026.
Herein, we propose a low‐cost authentication system based on a scalable fabrication technology and user friendly recognition system. It involves inkjet printing as a manufacturing method and an optical recognition system based on contour features extraction.

Summer Rainfall Drives Adaptation with Gene Flow in a Widespread Butterfly

Molecular Ecology, Volume 35, Issue 12, June 2026.
ABSTRACT Understanding how environmental variation interacts with gene flow to shape population genomic patterns is a central goal in evolutionary biology. We investigated how geographic and environmental differences impact genetic variation in the clouded sulfur butterfly (Colias philodice eriphyle) by conducting whole‐genome resequencing across ...

The co-Pieri rule for Kronecker coefficients

, 2017
A fundamental problem in the representation theory of the symmetric group, Sn, is to describe the coefficients in the decomposition of a tensor product of two simple representations. These coefficients are known in the literature as the Kronecker coefficients.
