C-R-T Fractionalization, Fermions, and Mod 8 Periodicity

Zheyan Wan, Juven Wang, Shing-Tung Yau +1

Charge conjugation (C), mirror reflection (R), time reversal (T), and fermion parity are basic discrete spacetime and internal symmetries of the Dirac fermions. In t…

Topological complexity of finding flex points on cubic plane curves

Weiyan Chen, Zheyan Wan

We prove a lower bound for the topological complexity, in the sense of Smale, of the problem of finding a flex point on a cubic plane curve. The key is to bound the Schwarz genus o…

The photography method: solving pentagon equation

Vassily Olegovich Manturov, Zheyan Wan

In the present paper, we consider two applications of the pentagon equation. The first deals with actions of flips on edges of triangulations labelled by rational functions in some…
