Combinatorics of Mumford-Morita-Miller classes in low genus

2003

Here we use elementary combinatorial arguments to give explicit formulae and relations for some cohomology classes of moduli spaces of stable curves of low genus.

Calculating cohomology groups of $overline M_0,n(mathbb P^r,d)$

2003

Here we investigate the rational cohomology of the moduli space ℳ̄0,n (ℙr,d) of degree d stable maps from n-pointed rational curves to ℙr. We obtain partial results for small values of d with an inductive method inspired by a paper of Enrico Arbarello and Maurizio Cornalba.

“Reclaiming public spaces”: Individuazione di strategie e metodi per la partecipazione della cittadinanza attiva nella produzione e gestione di spazi…

2014

A partire dall’analisi di due casi studio di (ri)appropriazione e riconversione temporanea a fini “pubblici” di aree inutilizzate, quali le appropriazioni/(ri)appropriazioni dell’ex-aeroporto di Tempelhof a Berlino e del “laghetto” in via Prenestina a Roma, l’articolo si propone di esplorare alcuni interrogativi quali: E’ possibile costituire una alternativa reale alla riduzione/sostituzione dello spazio pubblico, dovuta in gran parte ai problemi di bilancio che minacciano l’operatività delle amministrazioni locali, valorizzando le esperienze di auto-organizzazione, auto-gestione e partecipazione emerse nelle nostre città? Come interpretare/tradurre in strategie e metodi operativi la pressa…

Mobilizing against the Other : cyberhate, refugee crisis and proximization

2017

Drawing on the insights from Media Proximization Approach (MPA), the present chapter explores the dynamics of the online construction of the Other in the context of current refugee crisis and the phenomenon of hate speech within cyberspace. While content- and theme-wise, it takes under scrutiny online refugee-related discourses, on the theoretical and methodological level it presents a new approach to mediated construction of social reality based on the notion of distance and Self/Other or Us/Them dichotomy. Coached within (Cognitive) Critical Discourse Analysis, such an approach calls for an integration of corpus linguistics methods and tools. The chapter addresses the following questions:…

Destinationskrimis als identitätsstiftende Kulturräume. Die Stadt Valencia in Lokalkrimis deutscher Autoren

2021

En el presente artículo, la ciudad de Valencia puede considerarse escenario y destino de viaje al mismo tiempo. Sirve de telón de fondo a dos novelas policíacas alemanas cuyos autores han elegido Valencia como su nuevo hogar y cuyos protagonistas se mueven por la ciudad y sus alrededores. En el primer ejemplo, la interacción de autor y protagonista con este escenario local contribuye a la construcción de la ciudad como espacio cultural identitario y, en última instancia, pretende no sólo evocar sentimientos estéticos en el lector, sino también animar a viajar por la región. Por el contrario, la segunda novela, a pesar de la idéntica localización y de los antecedentes similares del autor, pr…

Mappings of Lp-integrable distortion: regularity of the inverse

2016

Let be an open set in ℝn and suppose that is a Sobolev homeomorphism. We study the regularity of f–1 under the Lp-integrability assumption on the distortion function Kf. First, if is the unit ball and p > n – 1, then the optimal local modulus of continuity of f–1 is attained by a radially symmetric mapping. We show that this is not the case when p ⩽ n – 1 and n ⩾ 3, and answer a question raised by S. Hencl and P. Koskela. Second, we obtain the optimal integrability results for ∣Df–1∣ in terms of the Lp-integrability assumptions of Kf.

Regularity and modulus of continuity of space-filling curves

2019

We study critical regularity assumptions on space-filling curves that possess certain modulus of continuity. The bounds we obtain are essentially sharp, as demonstrated by an example. peerReviewed

Rotational effects on the oscillation frequencies of newly born proto-neutron stars

2003

In this paper we study the effects of rotation on the frequencies of the quasi-normal modes of a proto-neutron star (PNS) born in a gravitational collapse during the first minute of life. Our analysis starts a few tenths of seconds after the PNS formation, when the stellar evolution can be described by a sequence of equilibrium configurations. We use the evolutionary models developed by Pons et al. (1999; 2001) that describe how a non rotating star cools down and contracts while neutrino diffusion and thermalization processes dominate the stellar dynamics. For assigned values of the evolution time, we set the star into slow rotation and integrate the equations of stellar perturbations in th…
