    <summary type="text">Title: On the convergence of some iterative methods; Sulla convergenza di certi metodi iterativi
Authors: Moret, Igor
Abstract: Si presenta un metodo per provare la convergenza di certi processi&#xD;
iterativi e lo si applica ai metodi di tipo Newtoniano della forma&#xD;
x$_{n+1}=x_{n}-(Ax_{n})^{-1}F(x_{n})$, ottenendo al tempo stesso&#xD;
delle maggiorazioni a posteriori dell'errore in senso stretto.; A method to prove the convergence of certain iterative processes is&#xD;
presented and applied to Newton-Type Methods of the form x$_{n+1}=x_{n}-(Ax_{n})^{-1}F(x_{n})$,&#xD;
moreover this allows to obtain sharp a posteriori error bounds.

    <summary type="text">Title: A system of axioms for the relation of betweenness; Un'assiomatica per la relazione «fra»
Authors: Trombetta, Maurizio
Abstract: Come estensione di un risultato di Wanda Szmielew riguardante relazioni d’ordine totale, si assegna un sistema di assiomi per la relazione ternaria «fra» da cui si deduce un ordinamento (parziale) nel quale la data relazione ternaria ha il significato usuale.; As an extension of a result of Wanda Szmielew concerning total order relations, we give here a system of axioms for the betweennes relation, whence a (partial) order is deduced, where the given ternary relation has the usual meaning.

    <summary type="text">Title: Pragmatic entropy for finitely additive probabilities
Authors: Sgarro, Andrea
Abstract: Si estende la definizione di entropia a distribuzioni di probabilità numerabili finitamente additive. L’impostazione scelta è pragmatica (fa uso di teoremi di codifica). L’entropia di una distribuzione di probabilità finitamente additiva in senso stretto viene posta pari a + infinto, poiché la corrispondente sorgen¬te stazionaria senza memoria non è comprimibile mediante codici-blocco; in effetti, a parte casi banali, le sorgenti finitamente additive in senso stretto non sono mai comprimibili mediante codici-blocco.; The definition of entropy is extended to countable fini¬tely additive probability distributions. The approach taken is pragmatic (makes use of coding theorems). The entropy of a properly finitely additive probability distribution is set equal to + infinite, because the corresponding stationary memoryless source is non-compressible through block-coding; as a matter of fact, apart from trivial cases, properly finitely additive sources are never compressible through block-coding.
