Bellisard et al., introduced a one-dimensional, almost-periodic, discrete Schroedinger operator which is defined by a parameter lambda. We allow this parameter to become complex and develop a geometric formalism to control the operator. The support of the spectrum of this operator is the Julia set of the mapping x/sup 2/ - lambda ..-->.. x. We prove that the almost-periodicity holds over wide regions of the complex lambda-plane, even though Hermiticity fails. 14 references.
