Global Fluctuations of Gaussian Elliptic Matrices
Lingxuan Wu, Zhi Yin
We introduce a spoke-arc decomposition of non-crossing annular pair partitions that records spoke type and orientation, isolates spoke-level contributions, and factoriz…

Outlier eigenvalues for full rank deformed single ring random matrices
Ching-Wei Ho, Zhi Yin, Ping Zhong
Let be an deterministic matrix and be a deterministic non-negative matrix such that and converge in -moments to operators and respec…

Spectrum of Laplacian matrices associated with large random elliptic matrices
Sean O'Rourke, Zhi Yin, Ping Zhong
A Laplacian matrix is a square matrix whose row sums are zero. We study the limiting eigenvalue distribution of a Laplacian matrix formed by taking a random elliptic matrix and sub…
