Kleber's conjecture and complementary products of symmetric functions
Reuven Hodges, Hanzhang Yin
We prove Kleber's rectangular-complement conjecture for Schur functions over an arbitrary commutative ring , showing that, for a fixed rectangle, the products , i…

The record statistic and forward stability of Schubert products
Andrew Hardt, Reuven Hodges, Hanzhang Yin
We initiate a probabilistic study of forward stability for products of Schubert polynomials through the record statistic (left-to-right maxima) of permutations. Building on the exp…

A non-iterative straightening algorithm and orthogonality for skew Schur modules
Reuven Hodges, Hanzhang Yin
We generalize Fulton's determinantal construction of Schur modules to the skew setting, providing an explicit and functorial presentation using only elementary linear algebra and d…
