Rethinking Civil Society in Development: Scales and Situated Hegemonies

2016

Ethnic residential segregation is often explained with the claim that ‘immigrants don’t want to integrate—they prefer to stick together with co-ethnics’. By contrast, mixed neighbourhoods are seen as crucial for achieving social cohesion. In line with spatial assimilation theory there is a normative assumption that people interact with those living nearby. From interviews on neighbourhood qualities and locations valued by Oslo residents of Turkish, Somali and Polish backgrounds, we raise questions about the validity of two assumptions: that most immigrants want to live in the same neighbourhoods as co-ethnics; and that they want to live close to co-ethnics because they do not want to integr…

Towards a New European Neighbourhood Policy (ENP): What Benefits of the Deep and Comprehensive Free Trade Agreements (DCFTAs) for Shared Prosperity a…

2016

This article examines the problem of the ENP countries’ integration with the EU market from two perspectives: the macroeconomic situation as an integral component of the overall transformation process and the integration with the EU markets, and the political economy of the regional integration perspectives of these countries. This methodological approach serves as a tool for integrating a number of main goals related to the EU’s soft power that require the development and support of civil society in the neighbouring states. This contribution aims to offer insight in the implementation of the regional arrangements, taking into consideration new political and economic realities in the Eurasi…

Una aproximación a la Electra de Sófocles desde el prólogo y la párodos

2008

Sófocles se esfuerza por lograr una integración mayor del coro en la acción dramática, a la vez que focaliza la acción del héroe en el marco en el que éste se mueve. En los primeros versos de esta tragedia, en particular en el prólogo y en la párodos, a través de las estructuras iterativas, podemos vislumbrar las claves de los conflictos profundos de esta saga que aflorarán finalmente en la forma de matricidio. Y desde esos primeros versos, esas claves se proyectan a otros lugares de la tragedia formando un tejido complejo que arroja no poca luz sobre ella. Sophocles strove to bring about a greater integration of the chorus into the dramatic action at the same time as he focused the action …

Oscillatory Behavior of Second-Order Nonlinear Neutral Differential Equations

2014

Published version of an article in the journal: Abstract and Applied Analysis. Also available from the publisher at: http://dx.doi.org/10.1155/2014/143614 Open Access We study oscillatory behavior of solutions to a class of second-order nonlinear neutral differential equations under the assumptions that allow applications to differential equations with delayed and advanced arguments. New theorems do not need several restrictive assumptions required in related results reported in the literature. Several examples are provided to show that the results obtained are sharp even for second-order ordinary differential equations and improve related contributions to the subject.

THE TOPOLOGY OF BASIN BOUNDARIES IN A CLASS OF THREE-DIMENSIONAL DYNAMICAL SYSTEMS

1996

We will develop new methods to determine the topology of the basin boundary in a class of three-dimensional dynamical systems. One approach is to approximate the basin boundary by backward integration. Unfortunately, there are dynamical systems where it is hard to approximate the basin boundary by a numerical backward integration algorithm. We will introduce topological methods which will provide new information about the structure of the basin boundary. The topological invariants which we will use can be numerically computed.

Integrability of the one dimensional Schrödinger equation

2018

We present a definition of integrability for the one dimensional Schroedinger equation, which encompasses all known integrable systems, i.e. systems for which the spectrum can be explicitly computed. For this, we introduce the class of rigid functions, built as Liouvillian functions, but containing all solutions of rigid differential operators in the sense of Katz, and a notion of natural boundary conditions. We then make a complete classification of rational integrable potentials. Many new integrable cases are found, some of them physically interesting.

A New Approach to the Generalization of Darbo’s Fixed Point Problem by Using Simulation Functions with Application to Integral Equations

2019

We investigate the existence of fixed points of self-mappings via simulation functions and measure of noncompactness. We use different classes of additional functions to get some general contractive inequalities. As an application of our main conclusions, we survey the existence of a solution for a class of integral equations under some new conditions. An example will be given to support our results.

Painlevé analysis and exact solutions for the coupled Burgers system

2006

We perform the Painleve test to a system of two coupled Burgers-type equations which fails to satisfy the Painleve test. In order to obtain a class of solutions, we use a slightly modified version of the test. These solutions are expressed in terms of the Airy functions. We also give the travelling wave solutions, expressed in terms of the trigonometric and hyperbolic functions.

On deformation of Poisson manifolds of hydrodynamic type

2001

We study a class of deformations of infinite-dimensional Poisson manifolds of hydrodynamic type which are of interest in the theory of Frobenius manifolds. We prove two results. First, we show that the second cohomology group of these manifolds, in the Poisson-Lichnerowicz cohomology, is ``essentially'' trivial. Then, we prove a conjecture of B. Dubrovin about the triviality of homogeneous formal deformations of the above manifolds.
