| description | In this paper it is considered a holographic dark energy model with a non-linear interaction between the component of dark energy and dark matter in a FRW type flat universe. In this context, the cosmological evolution of the universe is analyzed taking into account the behavior of the deceleration parameters q and the equation of state wL. From this analysis it follows that the universe has a phase of accelerated expansion in late times. It also notes that in this scenario the dark energy density will have a Big Rip type singularity in the future. Finally, it is compared the model with currently available data for H(z).

Evolución cosmológica de un modelo de energía oscura con interacción no lineal. Oliveros García, A. Cosmología energía oscura. (Cosmology Dark Energy.) In this paper it is considered a holographic dark energy model with a non-linear interaction between the component of dark energy and dark matter in a FRW type flat universe. In this context, the cosmological evolution of the universe is analyzed taking into account the behavior of the deceleration parameters q and the equation of state wL. From this analysis it follows that the universe has a phase of accelerated expansion in late times. It also notes that in this scenario the dark energy density will have a Big Rip type singularity in the future. Finally, it is compared the model with currently available data for H(z). En este trabajo consideramos un modelo holográfico de energía oscura junto con una interacción no lineal nentre la componente de energía oscura y la de materia oscura en un universo plano tipo FRW. En este contexto, se analiza la evolución cosmológica del universo teniendo en cuenta el comportamiento de los parámetros de desaceleración q y de la ecuación de estado wΛ. A partir de este análisis se deduce que el universo presenta una fase de expansión acelerada en tiempos tardíos. Se observa también que en este escenario la densidad de energía oscura presenta una singularidad tipo Big Rip en el futuro. Finalmente, comparamos el modelo con los datos disponibles actualmente para H(z).
