Affine Higher Bruhat Orders
Sara Billey, Herman Chau, Kevin Liu
The higher Bruhat orders are partial orders originally constructed by Manin and Schechtman, with an equivalent construction from Ziegler. These partial orders generalize the weak o…
A ChatGPT-assisted Triangle Characterization of Affine Permutation Inversion Graphs
Sara C. Billey, Herman Chau, Kevin Liu
Inversion sets of permutations in the affine symmetric group were studied extensively by Björner and Brenti. One of their methods for encoding an inversion set is…
Commutation classes of reduced words and higher Bruhat orders for affine permutations
Sara Billey, Herman Chau, Kevin Liu
The higher Bruhat orders are partial orders that generalize the weak order on the symmetric group , and the second higher Bruhat order is a poset on commutation classes of red…
Machine Learning meets Algebraic Combinatorics: A Suite of Datasets Capturing Research-level Conjecturing Ability in Pure Mathematics
Herman Chau, Helen Jenne, Davis Brown +4
With recent dramatic increases in AI system capabilities, there has been growing interest in utilizing machine learning for reasoning-heavy, quantitative tasks, particularly mathem…
Machines and Mathematical Mutations: Using GNNs to Characterize Quiver Mutation Classes
Jesse He, Helen Jenne, Herman Chau +4
Machine learning is becoming an increasingly valuable tool in mathematics, enabling one to identify subtle patterns across collections of examples so vast that they would be imposs…
