Comparison results for Hessian equations via symmetrization

2007

where the λ’s are the eigenvalues of the Hessian matrix D2u of u and Sk is the kth elementary symmetric function. For example, for k = 1, S1(Du) = 1u, while, for k = n, Sn(D 2u) = detD2u. Equations involving these operators, and some more general equations of the form F(λ1, . . . , λn) = f in , (1.2) have been widely studied by many authors, who restrict their considerations to convenient cones of solutions with respect to which the operator in (1.2) is elliptic. Following [25] we define the cone 0k of ellipticity for (1.1) to be the connected component containing the positive cone 0 = {λ ∈ R : λi > 0 ∀i = 1, . . . , n} of the set where Sk is positive. Thus 0k is an open, convex, symmetric…

Spatial Structures of the Philippines: Urbanization and Regional Inequalities

2017

This chapter examines the fundamental spatial structures of the Philippines. It defines the role and organization of the different levels of the administrative hierarchy (provinces, regions, cities and municipalities) down to the barangay and sitio/purok levels. This leads to the definition of the “urban” in the Philippines and the rise of urbanization in recent decades, from the original urban settlements of the Spanish era, with their patterns following the same rules as in Latin America (fort, church and plaza), to today’s cities. Forms of housing have evolved over time, from the archetypal bamboo/nipa hut (bahay kubo) and the urban stone and wood house of the elites (bahay na bato), now…

Entanglement in continuous-variable systems: recent advances and current perspectives

2007

We review the theory of continuous-variable entanglement with special emphasis on foundational aspects, conceptual structures, and mathematical methods. Much attention is devoted to the discussion of separability criteria and entanglement properties of Gaussian states, for their great practical relevance in applications to quantum optics and quantum information, as well as for the very clean framework that they allow for the study of the structure of nonlocal correlations. We give a self-contained introduction to phase-space and symplectic methods in the study of Gaussian states of infinite-dimensional bosonic systems. We review the most important results on the separability and distillabil…

Desigualdades y mortalidad por cirrosis en varones (Zaragoza, 1996-2003)

2011

ResumenObjetivosAnalizar diferencias geográficas en la mortalidad por cirrosis hepática, en varones, en la provincia de Zaragoza, y su posible asociación con indicadores socioeconómicos, así como identificar la adecuación, en el ámbito rural, del índice de privación del proyecto MEDEA.MétodosLa unidad geográfica de análisis para Zaragoza capital fue la sección censal, y para el resto de la provincia el municipio. Para cada unidad de análisis se calculó la razón de mortalidad estandarizada cruda y suavizada mediante un modelo lineal generalizado mixto bayesiano. Se calculó un índice sintético de privación y se incluyó en el modelo en cuartiles. También se realizó el análisis exploratorio inc…

L'IMPATTO DEL PNRR SULLE DISEGUAGLIANZE TERRITORIALI: NOTE INTRODUTTIVE

2022

The paper draws on the introduction presented at the second session of the Seminar organized by the Italian Association of Constitutionalists on "PNRR and Constitutional Order." In particular, the paper contains brief introductory notes on the impact of the PNRR on territorial inequalities, the issue of the North/South divide, and the role of territorial autonomies in the governance of the PNRR.

On some inequalities for the identric, logarithmic and related means

2015

We offer new proofs, refinements as well as new results related to classical means of two variables, including the identric and logarithmic means.

Socio-economic inequalities and organized crime: An empirical analysis

2020

In this chapter we contribute to the recent literature (e.g., Istat, 2010, Acciari et al., 2016, Guell et al., 2017) that provides evidence that inequality is high and social mobility is low in the Italian regions and prov-inces where organized crime is widespread such as those of Southern Italy. We complement this line of work in two respects. First, using a novel pan-el dataset at the regional level for the period 1985-2014 we investigate the relationship between inequality and organized crime at the regional level, exploiting both time and cross-sectional variation. Second, we assess the role of social mobility in organized crime. Our main finding is that higher inequality leads to highe…
