de Sitter symmetries and inflationary scalar-vector models
Juan P. Beltrán Almeida, Josué Motoa-Manzano, César A. Valenzuela-Toledo
In this paper, we study the correspondence between a field theory in de Sitter space in -dimensions and a dual conformal field theory in a euclidean space in -dimensions.…
Optimal Control Approach for Implementation of Sterile Insect Techniques
Pierre-Alexandre Bliman, Daiver Cardona-Salgado, Yves Dumont +1
Vector or pest control is essential to reduce the risk of vector-borne diseases or crop losses. Among the available biological control tools, the Sterile Insect Technique (SIT) is…
Higgs Inflation with linear and quadratic curvature corrections
L. N. Granda, D. F. Jimenez
We consider a single scalar field inflation model with Higgs potential and curvature corrections given by non-minimal derivative coupling to gravity and coupling to the Gauss-Bonne…
Finite scale factor and future singularities
L. N. Granda
The main characteristic of the dark energy is its negative pressure. In a homogeneous and isotropic FRW background, we consider several models for the dark energy fluid, which lead…
CDM-like models with future singularities
L. N. Granda
We consider new models of dark energy with finite time future singularities, by introducing the pressure density as a function of the scale factor. This approach gives acceptable p…
Deviations to Tri-Bi-Maximal mixing in the limit of symmetry
Diana C. Rivera-Agudelo, S. L. Tostado, Abdel Pérez-Lorenzana
In the limit of an approximate symmetry in the neutrino mass matrix, we explore deviations to the Tri-Bi-Maximal mixing pattern in the neutrino sector. We consider two differ…
