Abstract
In this chapter we consider the same model as in Chapter 3, but for d ? 5 instead of d = 1. Our goal is to prove diffusive behavior. The tool to achieve this is the so-called lace expansion, a combinatorial technique that hinges on the idea that in high dimensions the soft polymer can be viewed as a “perturbation” of SRW. For the exposition below, we borrow from van der Hofstad [156], Section 2, and Slade [280], Chapter 3. Figs. 4.2-4.4 are borrowed from Gordon Slade, Fig. 4.5 from Bill Casselman and Gordon Slade.
