The nonsymmetric shuffle theorem
Jonah Blasiak, Mark Haiman, Jennifer Morse +2
The shuffle conjecture of Haglund et al. expresses the symmetric function as a sum over labeled Dyck paths. Here is an operator on symmetric functions defined…

Finite matrix multiplication algorithms from infinite groups
Jonah Blasiak, Henry Cohn, Joshua A. Grochow +2
The Cohn-Umans (FOCS '03) group-theoretic framework for matrix multiplication produces fast matrix multiplication algorithms from three subsets of a finite group satisfying a s…

Flagged LLT polynomials, nonsymmetric plethysm, and nonsymmetric Macdonald polynomials
Jonah Blasiak, Mark Haiman, Jennifer Morse +2
The plethystic transformation and LLT polynomials are central to the theory of symmetric Macdonald polynomials. In this work, we introduce and study nonsy…
