Ergodic Decomposition for Inverse Wishart Measures on Infinite Positive-Definite Matrices

The ergodic unitarily invariant measures on the space of infinite Hermitian matrices have been classified by Pickrell and Olshanski-Vershik. The much-studied complex inverse Wishart measures form a projective family, thus giving rise to a unitarily invariant measure on infinite positive-definite mat...

The ergodic unitarily invariant measures on the space of infinite Hermitian matrices have been classified by Pickrell and Olshanski-Vershik. The much-studied complex inverse Wishart measures form a projective family, thus giving rise to a unitarily invariant measure on infinite positive-definite matrices. In this paper, we completely solve the corresponding problem of ergodic decomposition for this measure.
I would like to thank Alexei Borodin and Grigori Olshanski for some useful comments and pointers to the literature. Finally, I would like to thank the anonymous referees for a careful reading of the paper and a number of useful suggestions and remarks. Research supported by ERC Advanced Grant 740900 (LogCorRM).
