This is a special issue dedicated to Professor Miguel Ferrero's 70th birthday, containing the proceedings of a meeting on Ring Theory held on his behalf, from September 25th to 28th, 2008, in Porto Alegre, Brazil. Prof. Ferrero certainly deserves recognition for his academic life as professor and researcher in mathematics.
He was born on September 14th, 1938 in Canada Rosquin, in the Province of Santa Fe, Argentina. He obtained his PhD degree in 1970 under the supervision of Orlando Villamayor at Universidad de Buenos Aires, Argentina.
Miguel Ferrero teaches mathematics since 1959, first at the Universidad Nacional de Rosario, Argentina (1959 - 1976), then at the Universidade Estadual de Campinas (Unicamp), Brazil (1976) and finally at the Universidade Federal do Rio Grande do Sul (Ufrgs), Brazil, since 1977. He developed a very nice school in Algebra in Brazil, in particular he supervised ten Master Degree students and ten PhD students.
Miguel Ferrero has published more than 78 scientific articles and his research interests include such topics as Galois theory, theory of radicals, ring extensions, polynomial and skew polynomial rings, partial group actions on rings and several other related subjects. We warmly congratulate our great friend Miguel Ferrero on this occasion and wish him good health and much success in his life.
