Positive solutions for the Neumann p-Laplacian

2017

We examine parametric nonlinear Neumann problems driven by the p-Laplacian with asymptotically ( $$p-1$$ )-linear reaction term f(z, x) (as $$x\rightarrow +\infty $$ ). We determine the existence, nonexistence and minimality of positive solutions as the parameter $$\lambda >0$$ varies.

On multiplicities of cocharacters for algebras with superinvolution

2021

Abstract In this paper we deal with finitely generated superalgebras with superinvolution, satisfying a non-trivial identity, whose multiplicities of the cocharacters are bounded by a constant. Along the way, we prove that the codimension sequence of such algebras is polynomially bounded if and only if their colength sequence is bounded by a constant.

Perturbed eigenvalue problems for the Robin p-Laplacian plus an indefinite potential

2020

AbstractWe consider a parametric nonlinear Robin problem driven by the negativep-Laplacian plus an indefinite potential. The equation can be thought as a perturbation of the usual eigenvalue problem. We consider the case where the perturbation$$f(z,\cdot )$$f(z,·)is$$(p-1)$$(p-1)-sublinear and then the case where it is$$(p-1)$$(p-1)-superlinear but without satisfying the Ambrosetti–Rabinowitz condition. We establish existence and uniqueness or multiplicity of positive solutions for certain admissible range for the parameter$$\lambda \in {\mathbb {R}}$$λ∈Rwhich we specify exactly in terms of principal eigenvalue of the differential operator.

Uno stacco verso il cielo nei territori dell'EUR

2019

La torre Eurosky, dello Studio Purini/Thermes, accarezza il cielo di Roma. Da lontano la sua grammatica espressiva sembra suggerire l’emergere di un nuovo confronto fra un’architettura realizzata e la città in divenire. Questa si colloca come elemento di forte identità in un più ampio contesto che - messo a punto in un masterplan, sempre da Purini - definisce l’intera area di progetto dell’Europarco Castellaccio, a ridosso dell’EUR. The Eurosky tower, by Studio Purini / Thermes, caresses the sky of Rome. From a distance, its expressive grammar seems to suggest the emergence of a new comparison between a completed architecture and the city in the making. This is placed as an element of stron…

Enriching gender in physics education research: A binary past and a complex future

2016

[This paper is part of the Focused Collection on Gender in Physics.] In this article, we draw on previous reports from physics, science education, and women’s studies to propose a more nuanced treatment of gender in physics education research (PER). A growing body of PER examines gender differences in participation, performance, and attitudes toward physics. We have three critiques of this work: (i) it does not question whether the achievements of men are the most appropriate standard, (ii) individual experiences and student identities are undervalued, and (iii) the binary model of gender is not questioned. Driven by these critiques, we propose a conception of gender that is more up to date…

PUBLIC SPACES: resources for the city or places of conflict?

2019

Public spaces, whether they be indoors or out, are an important part of cities. They are the places of everyday life that have, over time, undergone a phase of decline. Today, in fact, they are under used, unattractive, unsafe and reflect the state of health of urban centers and their inhabitants. This study investigates the quality of public spaces of some urban realities - national and international - which have become examples of sustainable urban regeneration, places of sociality and hospitality.

Contextuality is About Identity of Random Variables

2014

Contextual situations are those in which seemingly "the same" random variable changes its identity depending on the conditions under which it is recorded. Such a change of identity is observed whenever the assumption that the variable is one and the same under different conditions leads to contradictions when one considers its joint distribution with other random variables (this is the essence of all Bell-type theorems). In our Contextuality-by-Default approach, instead of asking why or how the conditions force "one and the same" random variable to change "its" identity, any two random variables recorded under different conditions are considered different "automatically". They are never the…

One-loop results for the quark-gluon vertex in arbitrary dimension

2000

Results on the one-loop quark-gluon vertex with massive quarks are reviewed, in an arbitrary covariant gauge and in arbitrary space-time dimension. We show how it is possible to get on-shell results from the general off-shell expressions. The corresponding Ward-Slavnov-Taylor identity is discussed.

GENDER VIOLENCE IN THE POST-PATRIARCHALIZATION OF GLOBAL AGE: A COMPARATIVE PERSPECTIVE OF ITALY AND SERBIA

2014

RODNO NASILJE U POST-PATRIJARHALNOM GLOBALNOM DOBU: KOMPARATIVNA PERSPEKTIVA ITALIJE I SRBIJE Cilj ovog rada je da ponudi razumevanje interpretativnog dualizma između italijanskog i srpskog društva u pogledu rodnog nasilja nad ženama. U radu se, u komparativnom pristupu, ukazuje na elemente kontinuiranog opadanja muške dominacije u Italiji i opadanja patrijarhalne moći u Srbiji, kao rezultate varijeteta istorijskih i socijalnih uzroka. Emancipacija žena predstavlja snagu koja se suprotstavlja nasilju od partnera u nekim porodičnim kontekstima. Dok globalizacija i nezaposlenost čine deprivaciju muškaraca u u pogledu tradicionalne moći, sa druge strane, "muškarac u padu" čini "identitetski re…

Second-Generation Muslim Youth Between Perception and Change: A Case Study on the Prevention of Radicalization

2020

The following article presents the results of a research-action and an online communication campaign on the prevention of radicalization of second-generation young Italian Muslims as a part of a project called “Oltre” (the Italian acronym means “Beyond”) financed by European Union. After a short presentation of the four steps of the prevention communication model PKIC, a deepening on the radicalization factors, and a focus on the research-action methodology, the results of the research on some fundamental issues like the relationship with family and the relation with media and social media of the young interviewees, are shown. Finally, in the last part of the article, the interventions carr…
