Abstract
A formal correspondence beetwen the surface magnetization of an Ising quantum chain, perturbed by the paper-folding aperiodic sequence, and the partition function of a classical Ising chain in an inhomogeneous external field is derived. The perturbation is marginal and the critic al exponent Bs associated with the surface magnetization is a continuo us function of the perturbation amplitude. We obtain this exponent by analysing the classical chain.
