| Title: Asymptotic Gap Probability Distrbitions of the Gaussian Unitary Ensembles and the Jacobi Unitary Ensembles | |
| Abstract: We address a class of problems in Unitary Ensemble. Specifically, we study the probability tyhat a gap sysmetric about 0, i.e., $(-a,a)$ is found in the Gaussian Unitary ensembles (GUE) and the Jacobi Unitary ensembles (JUE) (where in the JUE, we take the parameters $\alpha=\beta$.) By exploiting the even parity of the weight, a doubling of the interval to $(a^2,\infty)$ for the GUE, and $(a^2,1)$ for the (symmetric) JUE, shows that the gap probabilities maybe determined as the product of the smallest eigenvalue distributions the LUE with parameter $\alpha=-1/2$ and$\alpha=1/2$ and the (shifted) JUE with weights x^{1/2} (1-x)^{\beta) and $x^{-1/2} (1-x)^{\beta}$. | |
