1. Qualitative description of the universe in the interacting fluids scheme / Cruz, Miguel ; Lepe, Samuel ; Morales-Navarrete, Gerardo
In this work we present a qualitative description of the evolution of a curved universe when we consider the interacting scheme for the constituents of the dark sector. [...]

2. Dark energy and dark matter interaction in light of the second law of thermodynamics / Cárdenas, Víctor H. ; Grandón, Daniela ; Lepe, Samuel
In the context of thermodynamics we discuss the way inevitable emerge an interaction between dark components, and in this way, provide a mechanism to understand the limits of the LCDM model and the class of interaction models between dark components. [...]

3. A holographic cut-off inspired in the apparent horizon / Cruz, Miguel ; Lepe, Samuel
In this work we consider a general function for the c2 term that appears in the conventional expression for the holographic dark energy in a FLRW curved spacetime. [...]

4. Gauss–Bonnet dark energy on Hořava–Lifshitz cosmology / Lepe, Samuel ; Otalora, Giovanni
We investigate the Gauss–Bonnet dark energy model and its deformed version on Hořava–Lifshitz cosmology, which belongs to the class of cosmologies obtained from the so-called projectable version of Hořava–Lifshitz gravity. [...]

5. Phantom solution in a non-linear Israel–Stewart theory / Cruz, Miguel ; Cruz, Norman ; Lepe, Samuel
In this paper we present a phantom solution with a big rip singularity in a non-linear regime of the Israel–Stewart formalism. [...]

7. Interacting cosmic fluids and phase transitions under a holographic modeling for dark energy / Lepe, Samuel ; Peña, Francisco
We discuss the consequences of possible sign changes of the Q -function which measures the transfer of energy between dark energy and dark matter. [...]

8. DGP cosmological model with generalized Ricci dark energy / Aguilera, Yeremy ; Avelino, Arturo ; Cruz, Norman ; Lepe, Samuel ; et al
The brane-world model proposed by Dvali, Gabadadze and Porrati (DGP) leads to an accelerated universe without cosmological constant or other form of dark energy for the positive branch (ϵ=+1) . [...]
