摘 要：we consider the extreme behavior of the top eigenvalues of the β-jacobi ensemble, which plays an important role in multivariate analysis. for general case, we establish a new large deviation principle for the top eigenvalues, and then we obtain the logarithmical efficiency of the is. meanwhile, for the very rectangular case, we show the strong efficiency of the is and also prove that the is converges to the optimal estimator with respect to the total variation distance. the talk is based on a joint work withyutaoma.
