Let the column vectors of X: M\_N, M<N, be distributed as independent complex normal vectors with the same covariance matrix 7. Then the usual quadratic form in the complex normal vectors is denoted by Z=XLX H where L: N\_N is a positive definite hermitian matrix. This paper deals with a representat

Consider the quadratic form Z=Y H (XL X H ) &1 Y where Y is a p\_m complex Gaussian matrix, X is an independent p\_n complex Gaussian matrix, L is a Hermitian positive definite matrix, and m p n. The distribution of Z has been studied for over 30 years due to its importance in certain multivariate s
## Abstract In this paper, we investigate the complex oscillation theory of the second order linear differential equation __f__ β³ + __A__ (__z__)__f__ = 0, where the coefficient __A__ (__z__) is an analytic function in the unit disc Ξ = {__z__: |__z__ | < 1} (Β© 2009 WILEYβVCH Verlag GmbH & Co. K
