Matrix models for beta ensembles
@article{Dumitriu2002MatrixMF, title={Matrix models for beta ensembles}, author={Ioana Dumitriu and Alan Edelman}, journal={Journal of Mathematical Physics}, year={2002}, volume={43}, pages={5830-5847} }
This paper constructs tridiagonal random matrix models for general (β>0) β-Hermite (Gaussian) and β-Laguerre (Wishart) ensembles. These generalize the well-known Gaussian and Wishart models for β=1,2,4. Furthermore, in the cases of the β-Laguerre ensembles, we eliminate the exponent quantization present in the previously known models. We further discuss applications for the new matrix models, and present some open problems.

Fast sampling from β-ensembles
- Computer Science

This work provides a unifying and elementary treatment of the tridiagonal models associated to the three classical Hermite, Laguerre and Jacobi ensembles and derives an approximate sampler for the simulation of β-ensembles, which supports a conjecture by Krishnapur et al. (2016), that the Gibbs chain on Jacobi matrices of size N mixes in O(logN).
