Random Walks, Critical Phenomena, and Triviality in Quantum Field Theory by Roberto Fernandez, Jürg Fröhlich, Alan D. Sokal.
Simple random walks - or equivalently, sums of independent random vari ables - have long been a standard topic of probability theory and mathemat ical physics. In the 1950s, non-Markovian random-walk models, such as the self-avoiding walk,were introduced into theoretical polymer physics, and gradu...
