Some distribution functions of the Laguerre ensemble
  In this paper we revisit the smallest-eigenvalue distribution of the Laguerre ensembles by presenting in closed form certain integrals obtained previously. With this information we compute, using Dyson's continuum approximation, the two-smallest-eigenvalue distribution of the Laguerre ensemble. High-order contributions to the free energies describing these two probabilities in certain scaling limits or \beta\neq 2, which can be interpreted in this context as an entropic effect, are found.
