The classical infinite divisibility of distributions related to eigenvalues of some random matrix ensembles is investigated. It is proved that the ββ-Tracy–Widom distribution, which is the limiting distribution of the largest eigenvalue of a ββ-Hermite ensemble, is not infinitely divisible. Furthermore, for each fixed N≥2N≥2 it is proved that the largest eigenvalue of a GOE/GUE random matrix is not infinitely divisible.
