    Description / Table of Contents: Riassunto Un metodo di rinormalizzazione basato sul campo medio con correzioni di campo di reazione è applicato a modelli di Ising diluiti. Sone trattati sia il caso di legami diluiti in due dimensioni, che quello di siti diluiti in due e tre dimensioni. Per diluizioni non troppo elevate il diagramma delle fasi è in buon accordo con altre predizioni. Ad alte diluizioni (vicino alla soglia di percolazione) possono verificarsi patologie dovute all’inadeguatezza del campo di reazione a basse temperature.
    Abstract: Резюме Группа перенормировки для среднего поля, включая поле взаимодействия, применяется к системам Изинга. Рассматриваются двумерное разбавление связи и двумерное и трехмерное разбавление узлов. Для слабого и среднего разбавления фазовые диаграммы хорошо согласуются с другими предсказаниями, однако для сильного раэбавления (вблизи порога перколяции) могут возникать патологии, связанные с выбором взаимодейстния при низкой температуре.
    Notes: Summary A mean-field renormalization group method including the reaction field is applied to diluted Ising systems. Two-dimensional bond dilution and both two- and three-dimensional site dilution are considered. For low and intermediate dilution, the phase diagrams agree well with other predictions, while for large dilution (near the percolation threshold) pathologies may show up related to the choice of the reaction field at low temperature.

    Notes: It is argued that a correct interpretation of the renormalization group results for the two-tolerant trail, as derived by Marqusee and Deutch, leads to the conclusion that this model belongs to the universality class of the self-avoiding walk, contrary to what these authors claim.
