Minimal Matchings for dP3 Cluster Variables
Judy Hsin-Hui Chiang, Gregg Musiker, Son Nguyen
In previous work [LM17], Tri Lai and the second author studied a family of subgraphs of the dP3 brane tiling, called Aztec castles, whose dimer partition functions provide combinat…
Spectrum of random-to-random shuffling in the Hecke algebra
Ilani Axelrod-Freed, Sarah Brauner, Judy Hsin-Hui Chiang +2
We generalize random-to-random shuffling from a Markov chain on the symmetric group to one on the Type A Iwahori Hecke algebra, and show that its eigenvalues are polynomials in q w…
Bender-Knuth involutions on linear extensions of posets
Judy Hsin-Hui Chiang, Anh Trong Nam Hoang, Matthew Kendall +4
We study the permutation group generated by Bender-Knuth moves on linear extensions of a poset , an analog of the Berenstein-Kirillov group on column-strict tab…
Local Decomposition of Hexahedral Singular Nodes into Singular Curves
Paul Zhang, Judy Hsin-Hui Chiang, Xinyi +2
Hexahedral (hex) meshing is a long studied topic in geometry processing with many fascinating and challenging associated problems. Hex meshes vary in complexity from structured to…
