Abstract
We consider the feedback connection of a plant M with a random matrix gain Δ, and study the statistical properties of the loop gain L = MΔ, under the hypothesis that the random feedback A has a unitarily invariant distribution. This setup has interesting connections with two open problems related to the γ-entropy of the plant, and to a probabilistic version of the multivariate Nyquist criterion
