[null,null,null,"Sommario/riassunto","\"In Chapter 5 of [2] there is a mistake in one assumption, which do not affect the results of the paper in the previous chapters. Precisely, the assumption in equation (5.2) has to be replaced by equation (5.6) therein. This replacement propagates in Hypotheses 5.2 and 5.3, as well as in Sections 4 and 5 of [1] and in Hypothesis 4.1(ii) of [3]. For the readers' convenience, we write here all the proofs of the involved results, though they are very similar. We remark that in all cases, replacing the correct assumptions makes all the written results true, and in most cases the proofs we give here are simpler than before. Each section follows the notations and the enumeration of the corresponding paper\"--"]
