1. Persistence of order on ferromagnetic models in the presence of quasi random auto-similar fields / Persistência de ordem em modelos ferromagnéticos na presença de campos auto-similares quase aleatórios"
In this work we study the existence of long range order for ferromagnetic models in the presence of an external field whose configuration has a pattern typically random. We prove, via the Peierlsargument modified by Griffiths in his study of an antiferromagnet, that the two dimensional ferromagnetic Ising model for a staggered field exhibits long-range order
