Abstract
Langevin equations describing the phase transitions of a variety of microscopic models with an infinite number of absorbing states and no additional symmetries are proposed. Renormalization group analysis shows that all of these models have static exponents belonging in the universality class of Reggeon field theory. Connections to epidemic models with immunization are discussed.File in questo prodotto:
