On the order of indeterminate moment problems
2013
For an indeterminate moment problem we denote the orthonormal polynomials by P_n. We study the relation between the growth of the function P(z)=(\sum_{n=0}^\infty|P_n(z)|^2)^{1/2} and summability properties of the sequence (P_n(z)). Under certain assumptions on the recurrence coefficients from the three term recurrence relation zP_n(z)=b_nP_{n+1}(z)+a_nP_n(z)+b_{n-1}P_{n-1}(z), we show that the function P is of order \alpha with 0<\alpha<1, if and only if the sequence (P_n(z)) is absolutely summable to any power greater than 2\alpha. Furthermore, the order \alpha is equal to the exponent of convergence of the sequence (b_n). Similar results are obtained for logarithmic order and for more ge…

Recenti scavi e ricerche a Terravecchia di Cuti
2020
The aim of this paper is to illustrate the preliminary results of research (intrasite survey and excavation) carried out from 2013 to 2017 in the fortified settlement of Terravecchia di Cuti. The intrasite survey allowed to select the excavation area. Some walls, part of two distinct buildings, have been identified: the most interesting structure is a large room, perhaps a courtyard, around which there are at least three rooms. Remains of pithoi are in the rooms, and two on the courtyard floor. Remains of other walls have also been identified, different in orientation and composition compared to the structures described; these walls are older than the buildings 1 and 2. Finally, it seems th…
Noterelle al «Filostrato» e al «Ninfale fiesolano» di Giovanni Boccaccio
2022
Abstract: This paper presents three brief reading notes on as many passages of the Filostrato (IV 51:1-8; IV 56, 4-8) and the Ninfale fiesolano (229, 1-5) by Giovanni Boccaccio, in the search for probable classical and medieval latin sources and models that have so far escaped the attention of scholars.
Il «De Cavichiolo»: una commedia umanistica al crocevia di generi diversi
2016
The so-called De Cavichiolo, a brief dialogic text comprising 76 elegiac couplets, centred on the exchange between a dissatisfied wife and a sodomite husband, has posed many delicate and controversial problems to those scholars who have studied this work. The principal issues, strictly correlated and interdependent, concern the chronology of the pièce (hypothesis range between the XII-XIII and XV centuries) and the relationship connecting this text to Boccaccio’s tale of Pietro di Vinciolo (Decam. V 10). In this paper the author (after his critical edition of the De Cavichiolo) newly looks on the text, a play having his place in the first period of latin humanistic comedy (perchance around …
«Humanae ac divinae litterae». Gli scritti di cultura medievale e umanistica di Mauro Donnini
2016
Questo intervento trae spunto dalla pubblicazione di un volume di Mauro Donnini («Humanae ac divinae litterae». Scritti di cultura medievale e umanistica, Spoleto [PG], Centro Italiano di Studi sull’Alto Medioevo [CISAM], 2013), nel quale lo studioso presenta 46 dei suoi studi sulla cultura e la letteratura medievale e umanistica, scritti fra il 1979 e il 2012. I principali temi affrontati sono l’edizione critica di testi mediolatini e umanistici; problemi letterari, di lingua e stile; le versificazioni; il riuso delle "auctoritates" classiche; la narratologia e le tecniche di analisi del racconto. This paper takes remark by the publication of «Humanae ac divinae litterae». Scritti di cultu…
Gli inni a Venere di Troiolo (Filostr. 3.74-89) e di Panfilo (Pamph. 1-70)
2022
Nel saggio in questione viene proposto un inedito parallelo fra l’inno che Troiolo indirizza alla dea Venere, nel «Filostrato» di Giovanni Boccaccio (Filostr. 3.74-89) e l’inno che Panfilo, nella commedia elegiaca «Pamphilus», indirizza alla stessa dea dell’amore (Pamph. 1-70). Oltre a fornire una puntuale analisi dei punti di contatto fra i due testi, vengono inoltre avanzate alcune considerazioni sul valore e il significato che la figura della dea Venere assume nelle opere del Boccaccio. In the essay in question an unprecedented parallel is proposed between the hymn that Troilus addresses to the goddess Venus, in Giovanni Boccaccio's «Filostrato» (Filostr. 3.74-89) and the hymn that Panfi…
The action of the unitary group associated with a quadratic extension of fields
1999
Given a quadratic extension L/k of fields of characteristic different from 2 and a unitary space (V, f) of finite dimension over L, we give a representation, as simple as possible, of the form which f induces by restriction on a k-substructure of V. This, in turn, allows one to study the orbits of the unitary group U(V, f) in the set of k-substructures of V of a given dimension.

A proof of bistability for the dual futile cycle
2014
Abstract The multiple futile cycle is an important building block in networks of chemical reactions arising in molecular biology. A typical process which it describes is the addition of n phosphate groups to a protein. It can be modelled by a system of ordinary differential equations depending on parameters. The special case n = 2 is called the dual futile cycle. The main result of this paper is a proof that there are parameter values for which the system of ODE describing the dual futile cycle has two distinct stable stationary solutions. The proof is based on bifurcation theory and geometric singular perturbation theory. An important entity built of three coupled multiple futile cycles is…
