Abstract [en]

We study the individual digits for the absolute value of the characteristic polynomial for the Circular beta-Ensemble. We show that, in the large N limit, the leading digits obey Benford's Law and furthermore that the digits of position increasing with the size of the ensemble become uniformly distributed. The key to the proofs is a bound on the rate of convergence in total variation norm in the CLT for the logarithm of the absolute value of the characteristic polynomial.
