8 Random Matrix Theory
In addition to non-asymptotic results, we will need asymptotic analysis, which is more delicate. The section is organized as follows:
- 1.
- Density of eigenvalues in classical ensembles of random matrices
- 2.
- Semi-Circle Law and Marchenko–Pastur Law
- 3.
- BBP Transition
- 4.
- CLT for Eigenvalues
- 5.
- Spectrum Separation
- 6.
- Replica Method
This section mainly follows STATC206B (UC Berkeley, taught by Vadim Gorin) and STAT260 (UC Berkeley, taught by Song Mei, 2021). I also refered to the book [1].
