Extending the Bipartite Parking Space
Dora Woodruff
We prove an analogue of a theorem of Berget and Rhoades about extending the parking space to an -module . Specifically, we show that the…
Honeycombs and Sums of Hermitian Matrices, Revisited
Ankur Moitra, Alexander Postnikov, Dora Woodruff
We give a new proof of the celebrated theorem of Knutson and Tao that the spectra of triples of Hermitian matrices exactly correspond to positions of boundary rays of h…
Temperley-Lieb Immanants, Key Positivity, and Demazure Crystals
Rosa Paten, Dora Woodruff
The main goal of this paper is to extend three important Schur positivity results to key positivity, replacing all Schur polynomials in relevant expressions with flagged Schur poly…
Forest Polynomials and Pattern Avoidance
Annie Guo, Dora Woodruff
Forest polynomials, recently introduced by Nadeau and Tewari, can be thought of as a quasisymmetric analogue for Schubert polynomials. They have already been shown to exhibit inter…
