On Thursday, June 28th, 2018, at 11 am, prof. Marcello Lucia from the City University of New York will give a talk on A rigidity theorem for an overdetermined problemThe talk will take place at Palazzo delle Scienze, room C (ground floor). All interested people are kindly invited Antonio Greco ________________________________________________________ A rigidity theorem for an overdetermined problem Abstract On a bounded simply connected domain of RN, consider the Laplacian eigenvalue problem with overdetermined boundary conditions, where both constant Dirichlet and zero Neumann boundary data are prescribed. This overdetermined problem admits a solution for instance in a disc, as can [...]

Transcompiling and Analysing Firewalls

Abstract. Configuring and maintaining a firewall configuration is notoriously hard. On the one hand, network administrators have to know in detail the policy meaning, as well as the internals of the firewall systems and of their languages. On the other hand, policies are written in low-level, platform-specific languages where firewall rules are inspected and enforced along non trivial control flow paths. Further difficulties arise from Network Address Translation (NAT), an indispensable mechanism in IPv4 networking for performing port redirection and translation of addresses.

Lecturer: Marcello Lucia, Professor at the City University of New York Dates: from Monday, May 28th, to Wednesday, June 13th Location: Palazzo delle Scienze, via Ospedale 72, Cagliari Summary. Calculus of Variations is a fundamental branch of Mathematical Analysis which has been deeply developed since its foundation. Born in connection with problems from Mathematical Physics, it is an extremely actual field of research due the theoretical defies it poses to the intellect as well as to its wide range of applications.Subject: variational methods (including minimization of variational integrals and critical points theory) for solving partial elliptic equations of elliptic type, [...]

L’Associazione Universo è lieta di invitarvi al seminario “Bitcoin e Crittovalute: alla scoperta delle tecnologie blockchain e degli smart contracts”, che si terrà Mercoledì 7 Marzo, alle ore 17 presso l’Aula Magna di Fisica del Palazzo delle Scienze. L’incontro nasce dalla curiosità di conoscere il fenomeno delle crittovalute e le potenzialità che da esse scaturiscono. Il tema verrà trattato dal punto di vista tecnico ed economico e terminerà con una panoramica sulle opportunità lavorative legate alla tecnologia blockchain. L’incontro prevede tre interventi: Massimo Bartoletti (Università degli Studi di Cagliari). Introduzione a Bitcoin, blockchain e smart contracts. Francesco Piras (Presidente dell’Associazione [...]

Lunedì 19 febbraio, alle ore 12, il prof. Giulio Ciraolo dell’Università di Palermo terrà una conferenza dal titolo: “Stime quantitative per ipersuperifici a curvatura media quasi costante”. La conferenza si terrà al Palazzo delle Scienze, in una delle due aulette nel piano mezzanino (aula F) da non confondersi con l’aula F al piano terra. Tutti gli interessati sono cordialmente invitati Antonio Greco ________________________________________________________ Stime quantitative per ipersuperifici a curvatura media quasi costante Sunto. Discuteremo alcune versioni quantitative del Teorema di Alexandrov della bolla di sapone, che afferma che le sfere sono le sole ipersuperfici chiuse embedded a curvatura media costante. [...]
