The spectral boundary of block structured random matrices
Economic and ecological models can be extremely complex, with a large number of agents/species each featuring multiple interacting dynamical quantities. In an attempt to understand the generic stability properties of such systems, we define and study an ...

Some complex systems (e.g., an ecosystem) in direct contact with an environment can be assigned the temperature of the environment. Other complex systems, such as human beings, can maintain a core temperature of 36.5°C in environments with different temperatures, at least for a short period of time.

A Mathematical Model for the Dynamics of Income Distribution in the Presence of Production
In this paper, a mathematical model is formulated, suitable to explain the evolution of income distribution over a population in the presence of production. The model is conceived from the perspective of complexity. Indeed, the income distribution emerges as the result of a myriad of economic exchanges taking place between individuals. In fact, the aim

Is Economics an Empirical Science? If not, can it become one?
Today’s mainstream economics, embodied in Dynamic Stochastic General Equilibrium (DSGE) models, cannot be considered an empirical science in the modern sense of the term: it is not based on empirical data, is not descriptive of the real-world economy ...

In this paper, the sequential conformable Langevin‐type differential equation is studied. A representation of a solution consisting of the newly defined conformable bivariate Mittag‐Leffler function to its nonhomogeneous and linear version is obtained via the conformable Laplace transforms’ technique. Also, existence and uniqueness of a global solution

The Resolvent of Impulsive Singular Hahn–Sturm–Liouville Operators
In this study, the resolvent of the impulsive singular Hahn–Sturm– Liouville operator is considered. An integral representation for the resolvent of this operator is obtained.

Applying the Möbius Strip Model to Corporate Social Responsibility: Survey-Based Findings from Italian Social Enterprises [PDF]
In this work, we apply the electro-magnetism geometrical model of the Möbius Strip in the context of Corporate Social Responsibility (CSR) in order to test the relationship between CSR and organizational performance.
