NOMA-2013: Workshop in Zaragoza – September 2013

The NOMA’13 International Workshop on Nonlinear Maps and Applications will be held on September 3 and 4, 2013 in Zaragoza, Spain. This is the fourth edition of a series of international conferences whose previous meetings were held in Toulouse (Noma’07), Urbino (Noma’09) and Évora (Noma’11). This workshop brings together researchers from theoretical and application areas (mathematics, physics, economy, engineering) who are pioneering in the study of nonlinear discrete systems. The conference is organized and hosted by the Universidad de Zaragoza, in the Faculty of Science, located in the south center of Zaragoza.

Nonlinear iterative processes play an important role in physical, biological and social phenomena. Nonlinear mappings can directly model many systems in different domains, as Engineering, Physics, Economics, Biology, etc., or they can be obtained via numerical methods permitting to solve differential non linear equations. In both cases, the understanding of specific behaviours and bifurcations of this type of systems is of the greatest interest. This workshop is open to theoretical studies as well as applicative ones. Contributions in the fields of Economics, Electronics, Biology, Computational methods, Engineering, Telecommunications, besides other more fundamental lectures, are wellcome. Mathematicians, Physicists, Engineers, Economists, and in general the specialists in the field of Nonlinear Systems, are invited to share their last contributions and developments in nonlinear discrete systems by participating in this conference.

Symbiosis refers to the biological interaction between two organisms or species, living in close association. In this book, the authors present current research in the study of the evolution, biology and ecological effects of symbiosis. Topics discussed include the evolution of arbuscular mycorrhiza; legume properties and symbiosis; sea anemones and hermit crab symbiosis in temperate seas; the agronomic and ecological importance between legumes and rhizobia; the behavioral, physiological and ecological effects of organisms in symbiotic associations; and a neuronal model with symbiotic interactions.

The Bistable Brain: A Neuronal Model with Symbiotic Interactions
Ricardo Lopez-Ruiz and Danièle Fournier-Prunaret

Abstract:

In general, the behavior of large and complex aggregates of elementary components can not be understood nor extrapolated from the properties of a few components. The brain is a good example of this type of networked systems where some patterns of behavior are observed independently of the topology and of the number of coupled units. Following this insight, we have studied the dynamics of different aggregates of logistic maps according to a particular symbiotic coupling scheme that imitates the neuronal excitation coupling. All these aggregates show some common dynamical properties, concretely a bistable behavior that is reported here with a certain detail. Thus, the qualitative relationship with neural systems is suggested through a naive model of many of such networked logistic maps whose behavior mimics the waking-sleeping bistability displayed by brain systems. Due to its relevance, some regions of multistability are determined and sketched for all these logistic models.

Geometrical Derivation of Equilibrium Distributions in some Stochastic Systems,
Ricardo Lopez-Ruiz and Jaime Sañudo

Abstract:

Classical statistical physics deals with statistical systems in equilibrium. Two fundamental distributions to describe situations in equilibrium are the Boltzmann-Gibbs (exponential) distribution and the Maxwellian (Gaussian) distribution. The first one represents the distribution of the energy states of a system and the second one fits the distribution of velocities in an ideal gas. They can be explained from different perspectives. In this chapter, these distributions are obtained from a geometrical interpretation of different multi-agent systems evolving in phase space under the hypothesis of equiprobability. Alternatively, they can also be derived as the asymptotic equilibria of two nonlinear models recently proposed in the literature.

Notions of Chaotic Cryptography: Sketch of a Chaos Based Cryptosystem
Carmen Pellicer-Lostao and Ricardo Lopez-Ruiz

Abstract:

Chaotic cryptography describes the use of chaos theory (in particular physical dynamical systems working in chaotic regime as part of communication techniques and computation algorithms) to perform different cryptographic tasks in a cryptographic system. In the end, the question is, can chaotic systems provide alternative techniques able to enhance cryptographic algorithms?. This chapter can be a worthy material to guide the reader in order to answer himself this question. Thus, the objective of this chapter is to give a general vision of what chaotic cryptography is and a comprehensive example that illustrates the main techniques used in this field. In it, the authors are intended to present a series of selected topics of special interest in this field.

“I think the next century will be the century of complexity” Prof. Stephen W. Hawking (DAMPT, University of Cambridge, UK), San Jose Mercury News, Morning Final Edition, January 23 (2000)

Several different measures defining complexity have been recently proposed within the scientific disciplines of physics, biology, mathematics and computer science. Such measures of complexity are generally context dependent. In chemical physics, a set of statistical complexity measures have been introduced using the information theoretical tools centering around the electron probability density of an N-electron system and its additional characteristics. The current monograph presents a detailed description of such measures of complexity. Starting with the information theoretical foundations, this monograph discusses at length their applications in the electronic structure of atoms and molecules including reactivity. The subject matter of the title is covered by the leading research scientists in the field who present an up-to-date account of their contributions, including future projections.

Statistical Complexity: Applications in Electronic Structure is intended for practicing physical, theoretical and computational chemists, material scientists, bio physicists and mathematical physicists.

Statistical Complexity and Fisher-Shannon Information: Applications

In this chapter, a statistical measure of complexity and the Fisher-Shannon information product are introduced and their properties are discussed. These measures are based on the interplay between the Shannon information, or a function of it, and the separation of the set of accessible states to a system from the equiprobability distribution, i.e. the disequilibrium or the Fisher information, respectively. Different applications in discrete and continuous systems are shown. Some of them are concerned with quantum systems, from prototypical systems such as the H-atom, the harmonic oscillator and the square well to other ones such as He-like ions, Hooke’s atoms or just the periodic table. In all of them, these statistical indicators show an interesting behavior able to discern and highlight some conformational properties of those systems.

Complexity and Stochastic Synchronization in Coupled Map Lattices and Cellular Automata
Ricardo Lopez-Ruiz and Juan R. Sanchez

Abstract:

Nowadays the question ‘what is complexity?’ is a challenge to be answered. This question
is triggering a great quantity of works in the frontier of physics, biology, mathematics and
computer science. Even more when this century has been told to be the century of complexity (Hawking, 2000). Although there seems to be no urgency to answer the above question, many different proposals that have been developed to this respect can be found in the literature (Perakh, 2004). In this context, several articles concerning statistical complexity and stochastic processes are collected in this chapter.
