Abstract
We consider layered two-dimensional Ising and directed walk models and show that the two problems are inherently related. The information ab out the zero-field thermodynamical properties of the Ising model is co ntained in the transfer matrix of the directed walk. For several hiera rchical and aperiodic distributions of the couplings, critical exponen ts for the two problems are obtained exactly through renormalization.
