Linear Spectral Statistics for Entrywise-Transformed Spiked Wigner Matrices under Shifted Profile Admissibility
Tsz-Kin Chan, Ji Oon Lee
We prove a derivative-free analytic linear spectral statistics theorem for entrywise-transformed rank-one spiked Wigner matrices with a general microscopic noise law. The transform…
Universality of the fluctuations of the free energy in generalized Sherrington-Kirkpatrick models and the log likelihood ratio in spiked Wigner models
Hyunsuk Choo, Yoochan Han, Ji Oon Lee
We consider the fluctuations of the free energy in generalized Sherrington-Kirkpatrick models and the log likelihood ratio of spiked Wigner models in the high temperature/subcritic…
Local laws and spectral properties of deformed sparse random matrices
Ji Oon Lee, Inyoung Yeo
We consider deformed sparse random matrices of the form , where is a real symmetric sparse random matrix, is a random or deterministic, real, diagonal matrix whos…
Fluctuations of the largest eigenvalues of transformed spiked Wigner matrices
Aro Lee, Ji Oon Lee
We consider a spiked random matrix model obtained by applying a function entrywise to a signal-plus-noise symmetric data matrix. We prove that the largest eigenvalue of this model,…
Fluctuations of the free energy of the spherical Sherrington-Kirkpatrick model with heavy-tailed interaction
Taegyun Kim, Ji Oon Lee
We consider the 2-spin spherical Sherrington--Kirkpatrick model without external magnetic field where the interactions between the spins are given as random variables with heavy-ta…
Spectral Properties and Weak Detection in Stochastic Block Models
Yoochan Han, Ji Oon Lee, Wooseok Yang
We consider the spectral properties of balanced stochastic block models of which the average degree grows slower than the number of nodes (sparse regime) or proportional to it (den…
