Global Minimality of Matrix-Valued Heteroclinic Connections between Vacuum Orbits
Sisi Guan, Yu Cheng
We study global energy minimization for matrix-valued heteroclinic connections whose vacuum sets are continuous conjugacy orbits rather than isolated points. For two distinguished…

On the Communication Complexity of Maximum Matching and Negative-Weight Shortest Paths
Yu Cheng, Tianle Jiang, Pachara Sawettamalya +1
We revisit several fundamental graph problems in the deterministic two-party communication model. Our main contributions include: (1) a new -bit protocol fo…
