✦ Synopsis
Operators associated with polynomials orthogonal on the unit circle and their doubly infinite analogs are considered. We assume that the elements in the operators are obtained from a stationary stochastic process and we investigate the properties of the spectrum of these operators. Lyapunov exponents are introduced and we examine their relationship with the absolutely continuous components of the spectrum of the above operators. 1994 Academic Press, Inc.
