End-to-end Distance from the Green's Function for a Hierarchical Self-Avoiding Walk in Four Dimensions
David C. Brydges, John Z. Imbrie
In [BEI] we introduced a Levy process on a hierarchical lattice which is four dimensional, in the sense that the Green's function for the process equals 1/x^2. If the process is mo…

Branched Polymers and Dimensional Reduction
David C. Brydges, John Z. Imbrie
We establish an exact relation between self-avoiding branched polymers in D+2 continuum dimensions and the hard-core continuum gas at negative activity in D dimensions. We review c…
