Special Issue (2003), SIII Advances in Geometry © de Gruyter 2003 Adriano Barlotti Born in Florence on 12 October 1923, Adriano Barlotti developed an interest in mathematics, and particularly in geometry, already as a child, guided by his godfa- ther Hans Dreyer. In 1942 he began to study mathematics at the University of Florence, and immediately after his graduation he became an enthusiastic assistant of Luigi Campedelli. A fellow student of Adriano is now his wife and life-time companion. Influenced by Guido Zappa, Adriano Barlotti started to work in finite geometry, investigating arcs and caps in finite projective spaces. Other lines of research led to the Lenz-Barlotti classification of projective planes and to fundamental results on groups of projectivities. Invited by R. C. Bose, he spent the academic year 1964/65 at Chapel Hill, North Carolina. Adriano Barlotti was appointed professor in Palermo in 1967 and transferred to the re-established University of Perugia in the same year, where he helped to build the department of mathematics. In 1972 he accepted a chair in Bologna and in 1982 a chair in Florence, returning to his roots. At all these universities he provided strong support for his large group of successful students and hospitality for many foreign visitors. Together with Giuseppe Tallini he became a leading figure of abstract geometry in Italy and an organizer of many large international conferences. To his students and colleagues Adriano Barlotti is known as a kind teacher and as a faithful friend. This special issue of Advances in Geometry consists of papers which are dedicated to Adriano Barlotti on the occasion of his 80th birthday. The authors of these papers follow the example of Adriano Barlotti, by contributing—to use his own words— "alia Combinatoria e alia Geometria, ehe ho amato e non smettero mai di amare". T. Grundhöfer, G. Lunardon, K. Strambach.

Unione Matematica Italiana 1921 - 2012 Unione Matematica Italiana Soggetto produttore Unione Matematica Italiana Estremi cronologici 1921 - Tipologia Ente Tipologia ente ente di cultura, ricreativo, sportivo, turistico Profilo storico / Biografia La fondazione dell’Unione Matematica Italiana è strettamente legata alla costituzione del Consiglio Internazionale delle Ricerche e al voto da questo formulato a Bruxelles nel luglio 1919 nel quale si auspicava il sorgere di «Unioni Internazionali» per settori scientifici, ai quali avrebbero dovuto aderire dei «Comitati nazionali» costituiti «ad iniziativa delle Accademie nazionali scientifiche o dei Consigli Nazionali delle Ricerche». In Italia, non essendo ancora stato costituito il C.N.R., fu l’Accademia dei Lincei, nella persona del suo presidente Vito Volterra, a farsi promotrice della costituzione dei Comitati nazionali. Per il Comitato della matematica Vito Volterra propose nel 1920, insieme a un gruppo di matematici, fra cui Luigi Bianchi, Pietro Burgatti, Roberto Marcolongo, Carlo Somigliana e Giovanni Vacca, la costituzione di una Unione Matematica Italiana, redigendo un primo schema di programma che poneva fra gli scopi dell’Unione l’incoraggiamento alla scienza pura, il ravvicinamento tra la matematica pura e le altre scienze, l’orientamento ed il progresso dell’insegnamento e l’organizzazione, la preparazione e la partecipazione a congressi nazionali ed internazionali. La proposta fu accolta dall’Accademia dei Lincei nel marzo 1921 e quale presidente dell’Unione venne designato Salvatore Pincherle, illustre matematico dell'Università di Bologna. L’Unione Matematica Italiana (UMI) nacque ufficialmente il 31 marzo 1922 con la diffusione da parte di Salvatore Pincherle di una lettera con la quale presentava il programma della Società invitando i destinatari ad aderire all’iniziativa.

INVENTARIO DELLA CORRISPONDENZA a Cura Di Claudio Sorrentino Con Il Coordinamento Scientifico Di Paola Cagiano De Azevedo
ARCHIVIO GAETANO FICHERA INVENTARIO DELLA CORRISPONDENZA a cura di Claudio Sorrentino con il coordinamento scientifico di Paola Cagiano de Azevedo Roma 2020 1 NOTA INTRODUTTIVA Gaetano Fichera nacque ad Acireale, in provincia di Catania, l’8 febbraio 1922. Fu assai verosimilmente suo padre Giovanni, anch’egli insegnante di matematica, a infondergli la passione per questa disciplina. Dopo aver frequentato il primo biennio di matematica nell’Università di Catania (1937-1939), si laureò brillantemente a Roma nel 1941, a soli diciannove anni, sotto la guida di Mauro Picone (di cui fu allievo prediletto), eminente matematico e fondatore dell’Istituto nazionale per le applicazioni del calcolo, il quale nello stesso anno lo fece nominare assistente incaricato presso la sua cattedra. Libero docente dal 1948, la sua attività didattica fu svolta sempre a Roma, ad eccezione del periodo che va dal 1949 al 1956, durante il quale, dopo essere divenuto professore di ruolo, insegnò nell’Università di Trieste. Nel 1956 fu chiamato all’Università di Roma, dove successe proprio al suo Maestro Mauro Picone, nella quale occupò le cattedre di analisi matematica e analisi superiore. Alla sua attività ufficiale vanno aggiunti i periodi, a volte anche piuttosto lunghi, di insegnamento svolto in Università o istituzioni estere. Questi incarichi all’estero, tuttavia, non interferirono con la sua attività didattica in Italia. Fu membro dell’Accademia nazionale dei Lincei, di cui fu socio corrispondente dal 1963 e nazionale dal 1978, e di altre prestigiose istituzioni culturali nazionali e internazionali. Nel 1976 fu insignito dall’Accademia dei Lincei stessa del “Premio Feltrinelli”. Ai Lincei si era sempre dedicato, soprattutto negli ultimi anni, quando dal 1990 al 1996 diresse i «Rendiconti di matematica e applicazioni», ai quali diede forte impulso, migliorandone la qualità scientifica e incrementandone la diffusione a livello internazionale.

This article introduces, informally, the substance and the spirit of Grothendieck's theory of the Picard scheme, highlighting its elegant simplicity, natural generality, and ingenious originality against the larger historical record. 1. Introduction A scientific biography should be written in which we indicate the “flow” of mathematics ::: discussing a certain aspect of Grothendieck's work, indicating possible roots, then describing the leap Grothendieck made from those roots to general ideas, and finally setting forth the impact of those ideas. Frans Oort [60, p. 2] Alexander Grothendieck sketched his proof of the existence of the Picard scheme in his February 1962 Bourbaki talk. Then, in his May 1962 Bourbaki talk, he sketched his proofs of various general properties of the scheme. Shortly afterwards, these two talks were reprinted in [31], commonly known as FGA, along with his commentaries, which included statements of nine finiteness theorems that refine the single finiteness theorem in his May talk and answer several related questions. However, Grothendieck had already defined the Picard scheme, via the functor it represents, on pp. 195-15, 16 of his February 1960 Bourbaki talk. Furthermore, on p. 212-01 of his February 1961 Bourbaki talk, he had announced that the scheme can be constructed by combining results on quotients sketched in that talk along with results on the Hilbert scheme to be sketched in his forthcoming May 1961 Bourbaki talk. Those three talks plus three earlier talks, which prepare the way, were also reprinted in [31].

The Neapolita Case the Aim of My Talk Is to Sketch the Situation of Journals
The Neapolita case The aim of my talk is to sketch the situation of journals in Naples, pointing out those, which in my opinion, could be investigated in the spirit of Cirmath, and which can be inserted in the database. This is just a survey, to understand what kind of math journals were printed in Naples. I must say that to look for journals in Naples isn’t simple. For during the second world war part of the archives of public institutions have been destroyed. The fate of Neapolitan publishing is tied to the political history of the Kingdom of Naples. 22 January 1799 “Jacobin” Republic 23 June 1799 First Bourbon Restoration French decade 1806- 1815 1806-1808 Giuseppe Bonaparte 1808-1815 Giocchino Murat 1815/1816 Second Bourbon Restoration Insurrections and subsequent violent 1820 e 1848 Bourbon repression 1860 Unification of Italy The scientific publishing industry was very prosperous untill to the first two decades of the nineteenth century, many monographs and translations of foreign books were published. The situation changed after the insurection of 1820 and the consequent violent repression of the Bourbons. In 1822 a Decree, imposing a strong duty on the importation of books, greatly influenced Neapolitan publishing. The price of italians and foreign books increased, then consequently these books disappeared from libraries; especially the scientific and technical books which, due to their nature , were subject to constant changes. In this period the number of printers increased from 33 in 1806 to 120 in 1833. What happens ? It happens that many booksellers became also printers, due to difficult economic conditions.

The Italian Contribution to the International Commission On
The Italian contribution to the International Commission on Mathematical Instruction from its founding to the 1950s Livia Giacardi Dipartimento di Matematica dell’Università di Torino. Italy Abstract In my paper I will illustrate, also referring to unpublished documents, the Italian contribution to the activities of the International Commission on Mathematical Instruction (ICMI) from 1908 to the 1950s when the Commissione Italiana per l’Insegnamento Matematico, was created. I will focus on: the role of Guido Castelnuovo in the earliest period; the ICMI’s influence on academic policies and school reforms in Italy; the dissolution of ICMI following World War I and the Italian side of the story; the political role of Salvatore Pincherle in re-establishing international collaboration in 1928; the birth of the Italian Commission for Mathematics Teaching and the role of Guido Ascoli. Introduction The origins of the Italian Commission for Mathematics Teaching1 are linked to the founding of the International Commission on the Teaching of Mathematics (French, Commission Internationale de l’Enseignement Mathématique; German, Internationale Mathematische Unterrichtskommission; Italian, Commissione internazionale dell’Insegnamento Matematico), which, from the early 1950s on, was known as the International Commission on Mathematical Instruction (ICMI).2 Constituted in Rome during the fourth International Congress of Mathematicians (ICM IV, 6-11 April 1908), its first president was Felix Klein, well-known for his important reforms in the teaching of

On the K2 of Degenerations of Surfaces and the Multiple Point Formula
Annals of Mathematics, 165 (2007), 335–395 On the K2 of degenerations of surfaces and the multiple point formula By A. Calabri, C. Ciliberto, F. Flamini, and R. Miranda* Abstract In this paper we study some properties of reducible surfaces, in particular of unions of planes. When the surface is the central fibre of an embedded flat degeneration of surfaces in a projective space, we deduce some properties of the smooth surface which is the general fibre of the degeneration from some combinatorial properties of the central fibre. In particular, we show that there are strong constraints on the invariants of a smooth surface which degener- ates to configurations of planes with global normal crossings or other mild singularities. Our interest in these problems has been raised by a series of interesting articles by Guido Zappa in the 1950’s. 1. Introduction In this paper we study in detail several properties of flat degenerations of surfaces whose general fibre is a smooth projective algebraic surface and whose central fibre is a reduced, connected surface X ⊂ Pr, r 3, which will usually be assumed to be a union of planes. As a first application of this approach, we shall see that there are strong constraints on the invariants of a smooth projective surface which degener- ates to configurations of planes with global normal crossings or other mild singularities (cf. §8). Our results include formulas on the basic invariants of smoothable sur- faces, especially the K2 (see e.g. Theorem 6.1). These formulas are useful in studying a wide range of open problems, such as what happens in the curve case, where one considers stick curves, i.e.
