Study of the Nonelementary Singular Points and the Dynamics Near the Infinity in Predator-Prey Systems / Diz-Pita, Érika (Universidade de Santiago de Compostela) ; Llibre, Jaume (Universitat Autònoma de Barcelona) ; Otero-Espinar, M. Victoria (Universidade de Santiago de Compostela)
In this chapter, we present the results obtained in two predator-prey systems, paying special attention to the dynamics near the infinity and the nonelementary singular points. First, the desingularization technique known as blow-up technique allows one to study any type of singularities of analytic systems in dimension two even if they are not elementary. [...]

54 p, 1.0 MB Topological Moduli Space for Germs of Holomorphic Foliations / Marín Pérez, David (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Mattei, Jean-François (Institut de Mathématiques de Toulouse) ; Salem, Eliane (Sorbonne Université. Institut de Mathématiques de Jussieu-Paris Rive Gauche)
This work deals with the topological classification of germs of singular foliations on (ℂ2,0). Working in a suitable class of foliations we fix the topological invariants given by the separatrix set, the Camacho-Sad indices, and the projective holonomy representations and we compute the moduli space of topological classes in terms of the cohomology of a new algebraic object that we call group-graph. [...]

53 p, 1.1 MB Topological moduli space for germs of foliations II : universal deformations / Marín Pérez, David (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Mattei, Jean-François (Université Paul Sabatier. Institut de Mathématiques de Toulouse) ; Salem, Eliane (Sorbonne Université. Institut de Mathématiques de Jussieu-Paris Rive Gauche)
This work deals with the topological classification of singular foliation germs on (C2,0). Working in a suitable class of foliations we fix the topological invariants given by the separatrix set, the Camacho-Sad indices and the projective holonomy representations and we prove the existence of a topological universal deformation through which every equisingular deformation uniquely factorizes up to topological conjugacy. [...]

23 p, 406.6 KB Multi-scale integrated analysis of sustainability : a methodological tool to improve the quality of the narratives / Giampietro, Mario (Istituto Nazionale di Ricerca per gli Alimenti e la Nutrizione) ; Ramos Martín, Jesús (Istituto Nazionale di Ricerca per gli Alimenti e la Nutrizione)
The goal of this paper is to illustrate an innovative methodology, multi-scale integrated analysis, developed for dealing with the new challenges implied by multi-criteria analysis of sustainability: an integrated assessment of sustainability requires a multi-dimensional and multi-scale analysis (technical incommensurability); when comparing human values, it is not possible to define, in substantive terms, 'the best course of action' (social incommensurability); it is not possible to generate accurate and relevant scenarios when forecasting the future of adaptive systems evolving across scales.

This paper presents two applications of the multi-scale integrated analysis of societal metabolism (MSIASM) approach. The first application shows that accounting the metabolism of a society in both economic and biophysical terms supports a better understanding of mechanisms determining evolutionary trajectories. [...]

11 p, 967.8 KB Computation of topological phase diagram of disordered Pb1-x Snx Te using the kernel polynomial method / Varjas, Dániel (Delft University of Technology. Kavli Institute of Nanoscience) ; Fruchart, Michel (University of Chicago. James Franck Institute and Department of Physics) ; Akhmerov, Anton R. (Delft University of Technology. Kavli Institute of Nanoscience) ; Perez-Piskunow, Pablo M. (Institut Català de Nanociència i Nanotecnologia)
We present an algorithm to determine topological invariants of inhomogeneous systems, such as alloys, disordered crystals, or amorphous systems. Based on the kernel polynomial method, our algorithm allows us to study samples with more than 107 degrees of freedom. [...]

24 p, 4.9 MB Apropiación del espacio con agricultura : un estudio de aprendizaje asociativo mediante un modelo de simulación basado en agentes / Vélez Torres, Álvaro (Universidad Autónoma Chapingo (Mèxic)) ; Valdez Cepeda, Ricardo David (Universidad Autónoma Chapingo (Mèxic)) ; López Cruz, Irineo Lorenzo (Universidad Autónoma Chapingo (Mèxic))
Las formas de apropiación de un espacio siguen patrones de aprendizaje condicionado. Se sostiene que la forma que siguen estos patrones está sesgada por el aprendizaje adquirido en ensayos sucesivos. [...]
The forms of appropriation of space follow conditioned learning patterns. The way these patterns follow is held to be biased by learning acquired in successive trials. In this sense, we have tested a process of appropriation of the space of a donation area that in the past was appropriated with garbage, with rubble, with pruning remains and with eventual fires to burn the garbage. [...]

This paper aims to analyze Louise Erdrich's Future Home of the Living God from an ecocritical viewpoint, utilizing the perspective that the knowledge about the problematic emerging from the concept of the Anthropocene gives us, in order to carry out a wider research than that one provided by traditional ecocriticism.

Departament de Física) ; Lewenstein, Maciej (Institució Catalana de Recerca i Estudis Avançats)
We study the random walk of a particle in a compartmentalized environment, as realized in biological samples or solid state compounds. Each compartment is characterized by its length L and the boundaries transmittance T. [...]

17 p, 1.7 MB Perception and representation of the resource nexus at the interface between society and the natural environment / Giampietro, Mario (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals)
Recent years have seen an explosion of interest in the resource nexus. This has created the co-existence of different understandings and uses of the concept. In this regard, experiences in the EU H2020 project 'Moving towards adaptive governance in complexity: Informing nexus security' are consistent with findings reported in the literature: (i) The inconvenient message of the nexus is difficult to get across, it being incompatible with the currently dominant rosy narratives about sustainability.
