Differential positivity and dynamical order in noisy oscillators under unidirectional coupling

Bochun Chang, Xiaofang Lin, Yi Wang

We focus on a stochastic system that models a collection of $N$ identical oscillators with unidirectional coupling, perturbed by white noise. The unidirectional coupling breaks the…

Changes in the Seidel energy of blow-up graphs under edge deletion

Yayang Liu, Yi Wang

Let $S (G)$ denote the Seidel matrix of a simple graph $G$ , and let $E_{S} (G)$ be the Seidel energy of $G$ , defined as the sum of the absolute values of the eigenvalues of $S (G)$ . In…
