Søren Kierkegaard et Fernando Pessoa utilisèrent deux procédés littéraires similaires, la pseudonymie et l'hétéronymie, auxquels ils donnèrent un contenu différent. Le premier tente par ce biais de se rapprocher de l'Individu sans avoir à endosser l'esthétique, ni le religieux qu'il ne saurait atteindre pleinement ; le second, sous la figure de Caeiro, esquisse les traits d'un nouvel individu qu'illustrent à leur façon des êtres de fiction, les hétéronymes. Mais pour les deux auteurs, le souc...

Part of Philosophical Theology in Transition (Vol. II/2): Atheistic Philosophers after Hegel and den scotistisch Tradition, wich obscures an phaenomenological and existential understanding of being (creation) as a gift, reject the existence of God to protect human dignity, independence and liberty, developed their own ontologies and are not postmetaphysical thinkers.

Nonlinear science is the science of, among other exotic phenomena, unexpected and unpredictable behavior, catastrophes, complex interactions, and significant perturbations. Ocean and atmosphere dynamics, weather, many bodies in interaction, ultrahigh intensity excitations, life, formation of natural patterns, and coupled interactions between components or different scales are only a few examples of systems where nonlinear science is necessary. All outstanding, selfsustained, and stable structures in space and time exist and protrude out of a regular linear background of states mainly because they identify themselves from the rest by being highly localized in range, time, configuration, states, and phase spaces. Guessing how high up you drive toward the top of the mountain by compiling your speed, road slope, and trip duration is a linear model, but predicting the occurrence around a turn of a boulder fallen on the road is a nonlinear phenomenon. In an effort to grasp and understand nonlinear phenomena, scientists have developed several mathematical approaches including inverse scattering theory, Backlund and groups of transformations, bilinear method, and several other detailed technical procedures. In this Special Issue, we introduce a few very recent approaches together with their physical meaning and applications. We present here five important papers on waves, unsteady flows, phases separation, ocean dynamics, nonlinear optic, viral dynamics, and the selfappearance of patterns for spatially extended systems, which are problems that have aroused scientists’ interest for decades, yet still cannot be predicted and have their generating mechanism and stability open to debate. The aim of this Special Issue was to present these most debated and interesting topics from nonlinear science for which, despite the existence of highly developed mathematical tools of investigation, there are still fundamental open questions.

Fractional calculus provides the possibility of introducing integrals and derivatives of an arbitrary order in the mathematical modelling of physical processes, and it has become a relevant subject with applications to various fields, such as anomalous diffusion, propagation in different media, and propogation in relation to materials with different properties. However, many aspects from theoretical and practical points of view have still to be developed in relation to models based on fractional operators. This Special Issue is related to new developments on different aspects of fractional differential equations, both from a theoretical point of view and in terms of applications in different fields such as physics, chemistry, or control theory, for instance. The topics of the Issue include fractional calculus, the mathematical analysis of the properties of the solutions to fractional equations, the extension of classical approaches, or applications of fractional equations to several fields.

The institution of monasticism in the Christian Church is in general decline, at least in socalled “first world” nations. Though there are many reasons for this, monastic leaders are confronted by the reality of fewer communities, monks, and nuns nonetheless. At the same time, many younger Christians are rediscovering the rich heritage of the monastic tradition. Though they themselves might not be called to join a traditional monastery, they are eager to appropriate monastic practices in their own lives. This had led to a movement known as the “new monasticism” or “secular monasticism.” Despite lacking a unified vision and any central organization, these new/secular monastics are attempting, in their own ways, to carry on the tradition and practices of Christian monasticism. As well, there is a movement within historical Christian monasteries to pour new wine into old wineskins. Traditional forms of monasticism are also generally flourishing in developing nations, breathing new life into monasticism. This volume looks at the current monastic landscape to assess where monasticism stands and to imagine ways in which it will grow in the future, leading not only to a renewed Christian monasticism but to new monasticisms.

This Special Issue aims to be a compilation of new results in the areas of differential and difference Equations, covering boundary value problems, systems of differential and difference equations, as well as analytical and numerical methods. The objective is to provide an overview of techniques used in these different areas and to emphasize their applicability to reallife phenomena, by the inclusion of examples. These examples not only clarify the theoretical results presented, but also provide insight on how to apply, for future works, the techniques used.

In recent years, entropy has been used as a measure of the degree of chaos in dynamical systems. Thus, it is important to study entropy in nonlinear systems. Moreover, there has been increasing interest in the last few years regarding the novel classification of nonlinear dynamical systems including two kinds of attractors: selfexcited attractors and hidden attractors. The localization of selfexcited attractors by applying a standard computational procedure is straightforward. In systems with hidden attractors, however, a specific computational procedure must be developed, since equilibrium points do not help in the localization of hidden attractors. Some examples of this kind of system are chaotic dynamical systems with no equilibrium points; with only stable equilibria, curves of equilibria, and surfaces of equilibria; and with nonhyperbolic equilibria. There is evidence that hidden attractors play a vital role in various fields ranging from phaselocked loops, oscillators, describing convective fluid motion, drilling systems, information theory, cryptography, and multilevel DC/DC converters. This Special Issue is a collection of the latest scientific trends on the advanced topics of dynamics, entropy, fractional order calculus, and applications in complex systems with selfexcited attractors and hidden attractors.
