Query: Free Random Levy Variables and Financial Probabilities   We suggest that Free Random Variables, represented here by large random
matrices with spectral Levy disorder, may be relevant for several problems
related to the modeling of financial systems. In particular, we consider a
financial covariance matrix composed of asymmetric and free random Levy
matrices. We derive an algebraic equation for the resolvent and solve it to
extract the spectral density. The free eigenvalue spectrum is in remarkable
agreement with the one obtained from the covariance matrix of the SP500
financial market.
