POLYMERS, SPIN MODELS AND FIELD THEORY Bo S\"oderberg Abstract: The generic relation between continuous polymers and zero-component Euclidean field-theories is reviewed, and exemplified by polymers with contact and Coulomb interactions. An analogous relation on the lattice is also discussed, relating the statistics of self-avoiding walks to a zero-component spin-model.
