Weighted Hardy Spaces of Quasiconformal Mappings
2019
We establish a weighted version of the $H^p$-theory of quasiconformal mappings.
Encuentro de saberes: Huellas de memoria pluriversa y descolonización de la Universidad contemporánea
2018
This paper studies the Encounter of Knowledge as a project that, by welcoming mestres and mestras of ancestral knowledge into universities, contributes to decolonize higher education, broadening its field of memory. Based on a systematization exercise, we established a theoretical dialogue with Bajtin and Bejamin. Based on the participation of four mestres -Lucely Pío, raicera del Cerrado, Mãe Lu and Tata Mutá Imé, religious leaders of Candomblé and the political leader and shaman Álvaro Tukano of the Tukano nation- we show how the project promotes in the contemporary Brazilian university a space of mnemic pluriversity, capable of activating diverse narrative planes (biographical, political…
Biological and Mechanical Characterization of the Random Positioning Machine (RPM) for Microgravity Simulations
2021
The rapid improvement of space technologies is leading to the continuous increase of space missions that will soon bring humans back to the Moon and, in the coming future, toward longer interplanetary missions such as the one to Mars. The idea of living in space is charming and fascinating; however, the space environment is a harsh place to host human life and exposes the crew to many physical challenges. The absence of gravity experienced in space affects many aspects of human biology and can be reproduced in vitro with the help of microgravity simulators. Simulated microgravity (s-μg) is applied in many fields of research, ranging from cell biology to physics, including cancer biology. In…
On probabilistic interpretations of predicates
2016
In classical logic, any m-ary predicate is interpreted as an m-argument two-valued relation defined on a non-empty universe. In probability theory, m-ary predicates are interpreted as probability measures on the mth power of a probability space. m-ary probabilistic predicates are equivalently semantically characterized as m-dimensional cumulative distribution functions defined on Rm. The paper is mainly concerned with probabilistic interpretations of unary predicates in the algebra of cumulative distribution functions defined on R. This algebra, enriched with two constants, forms a bounded De Morgan algebra. Two logical systems based on the algebra of cumulative distributions are defined an…
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…
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.
