  • Soliton-like solutions of nonlinear scalar and electromagnetic field
           equations in gravitational theory

    • Authors: A. E. Yamadjako, A. Adomou, A. C. Houngan
      Pages: 1 - 8
      Abstract: In this work, exact analytical static spherical symmetric solutions to the nonlinear interacting electromagnetic and massless scalar field equations have been determined taking into account the proper gravitational field of elementary particles. The obtained results prove that all solutions of the Einstein equation and those of the interacting fields are regular with localized energy density. All non-zero components of the 4-vector potential are solutions to the inverted Painlevé-Gambier XI equation. Moreover, the total energy of interacting fields is limited and the total charge of elementary particles is finite. These solutions obtained are soliton-like and can be used as a model to describe the internal structure of elementary particles.

  • Principal centrality measures: a comprehensive approach to the Spanish
           stocks market

    • Authors: Amauri Gutierrez
      Pages: 9 - 16
      Abstract: In social network analysis, for determining the relevance or significance of a node in the network, several node centrality measures are often used such as degree centrality, betwenness centrality, closeness centrality, eigenvector, subgraph and page rank centrality. In this paper we apply a principal components analysis over the traditional centrality measures for obtaining an overall single metric that combines the best attributes of the traditional centrality measures and permits to detect relevant nodes in the network. Concretely, a detailed study of the Spanish stocks market will be used for demonstrating the advantages of this approach.

  • Behavior of the epidemic due to the covid-19 virus in Mexico. Development
           of an algorithm

    • Authors: Yael A. Almaguer-Salinas, Delfino Ladino-Luna, Ricardo T. Paez-Hernández
      Pages: 17 - 25
      Abstract: In the present paper, an algorithm was developed to represent the behavior of the current SARS-CoV-2 virus epidemic in Mexico, known as COVID-19, to obtain a likely scenario for the coming months and provoke a healthy discussion about the problem. The data reported by government entities is considered first by analyzing a simple model, via the construction of a polynomial, and then building an exponential type function, from the so-called logistic function. A numerical comparison is made with the officially provided data, and the graphs obtained from the solutions found are shown, including a brief explanation on how to interpret them appropriately. Finally, the possible scenario for the following months of the development of the epidemic in Mexico is discussed.
