Chiaroscuri dalla prima ricezione di Dante presso gli ordini mendicanti
No full textLa prima parte del saggio analizza due episodi significativi della più antica ricezione della Commedia in ambito religioso, gli antichi commenti dei cosiddetti Anonimo Lombardo e Anonimo Teologo. L’analisi congiunta dei due apparati notulari si giustifica alla luce della tradizione manoscritta comune (i due testi viaggiano sempre insieme) e di una comune formazione culturale, genericamente religiosa per il Lombardo, specificamente domenicana per il Teologo. Il problema del rapporto tra fictio e verità nella poesia dantesca, così come affrontata dai primi esegeti di estrazione mendicante, Guido da Pisa in particolare, e laica, su tutti Benvenuto da Imola, costituisce l’asse portante della seconda parte del saggio
Block Factorization of the Relative Entropy via Spatial Mixing
No full textWe consider spin systems in the d-dimensional lattice Zd satisfying the so-called strong spatial mixing condition. We show that the relative entropy functional of the corresponding Gibbs measure satisfies a family of inequalities which control the entropy on a given region V⊂ Zd in terms of a weighted sum of the entropies on blocks A⊂ V when each A is given an arbitrary nonnegative weight αA. These inequalities generalize the well known logarithmic Sobolev inequality for the Glauber dynamics. Moreover, they provide a natural extension of the classical Shearer inequality satisfied by the Shannon entropy. Finally, they imply a family of modified logarithmic Sobolev inequalities which give quantitative control on the convergence to equilibrium of arbitrary weighted block dynamics of heat bath type

Computer simulation:A new scientific approach to the study of language evolution
No full textLanguage is such an important human characteristics that we would like to know how it first came into existence and how it managed to reach its present form. If we could go back in time for a sufficient number of generations we would encounter human ancestors that did not have language. In a succession of generations the descendants of those non-linguistic ancestors came to possess the ability to speak and to understand the speech of others. What made the transition possible? How did the transition occur? Were there intermediate forms of language in the sense of communication systems different from known animal communication systems but also different from language as we know it and as is spoken today by all humans
