Peiffer product and peiffer commutator for internal pre-crossed modules

2017

In this work we introduce the notions of Peiffer product and Peiffer commutator of internal pre-crossed modules over a fixed object B, extending the corresponding classical notions to any semi-abelian category C. We prove that, under mild additional assumptions on C, crossed modules are characterized as those pre-crossed modules X whose Peiffer commutator 〈X, X〉 is trivial. Furthermore we provide suitable conditions on C (fulfilled by a large class of algebraic varieties, including among others groups, associative algebras, Lie and Leibniz algebras) under which the Peiffer product realizes the coproduct in the category of crossed modules over B.

Ripensare lo straniero. Lesbii e Parti nell'ottavo libro del Bellum civile di Lucano

2016

The eighth book of Lucan's bellum ciuile opens with the loss of Pompeius fleeing from the Thessalian battlefield. This departure, which sees the old fighter now prostrate and on which hangs a heavy fate of death, includes a double description of peoples and nations. The inhabitants of Lesbos, in which Cornelia had found shelter, offer a safe haven to Pompeius, urging him to remain. Moreover Pompeius seem to be inclined to the Parthians, the traditional enemy of Rome, but the option is destined to be defeated at the urging of Lentulus, which will convince the council of war to turn to Egypt. Within this opposing and contradictory motivations, where the reasons of the history emerge strongly …

Dalla parte dei Decii. Lucano e la storia esemplare di Roma

2021

The paper deals with the references to the exemplary history of the Decii in Lucan’s Pharsalia. Particular attention is focused on the model of virtue and self-sacrifice towards the State they embody. However, while they ennoble the pars Pompeiana, they nevertheless show the fragility of Pompey’s fate, increasing the sense of an imminent catastrophe: the virtuous model of the Decii is in fact not replicable. The subversion produced by civil war makes it now out of date: tragedy, not history

Roma, faue coeptis. Pompeo e i Parti nell’ottavo libro della Pharsalia di Lucano

2015

The paper focuses on the section of eighth book of Pharsalia, in which Pompeius discusses with the members of the senate in order to decide the place to find refuge. Particularly, the choice that will bring Pompeius to death in Egypt is determined by the speech of Lentulus: in order to reject proposals for an alliance with the Parthians, he adopts the perspective of the ancient ethnocentrism and his prejudices. Nevertheless, in the architecture of the episode, it is determinant the rhetorical culture of the Author.

Quid meruere nepotes. Responsabilità e merito nella Pharsalia di Lucano

2017

Il contributo indaga l’epos lucaneo ricostruendo i contesti in cui compaiono nel poema meritum e derivati, immagini che coinvolgono tanto la nozione di merito quanto quella di responsabilità. Si tratta di un’oscillazione ben visibile ed operante all’interno dell’opera, dove tali accezioni tornano con frequenza a scandire tanto le azioni dei protagonisti quanto i severi giudizi del narratore. The paper deals with Lucan’s Pharsalia, reconstructing the contexts in which meritum and derivatives appear, images that both involve the notion of merit as that of responsibility. It is a highly visible and active presence within the poem, where such meanings frequently appear, characterizing both the …
