On surface integrals related to distributions of random matrices
A. S. Shvedov National Research University "Higher School of Economics", Moscow
Abstract:
We construct the first quadratic form and the volume element of the surface consisting of all positive semidefinite $m\times m$ matrices of rank $r$ with $r$ distinct positive eigenvalues. We give the density function of the singular gamma distribution.
Keywords:
first quadratic form, volume element, singular gamma distribution, random matrix.
