Hypergeometric functions of many matrix variables and distributions of generalized quadratic forms. (English) Zbl 0855.62037
Linear functions of matrix-variate gamma random variables, in the real case, and their distributions are discussed. Properties of Lauricella functions of matrix arguments are used in deriving different representations of the moment generating functions thereby evaluating the density without going through standard methods. Distributions of determinants and generalized quadratic forms are also considered. The results are given in terms of special functions of several matrix arguments as well as in \(G\)-functions of scalar variables.
