# An interacting holographic dark energy model within an induced gravity brane

## TL;DR

This paper proposes a cosmological model combining holographic Ricci dark energy with an induced gravity brane-world, addressing rip singularities and showing phantom-like behavior in late-time universe evolution.

## Contribution

It introduces a novel interacting dark energy-dark matter model within an induced gravity brane-world framework, removing rip singularities and demonstrating phantom-like dark energy behavior.

## Key findings

- Rip singularities are eliminated in the model.
- Holographic Ricci dark energy exhibits phantom-like behavior.
- The universe approaches a de Sitter phase asymptotically.

## Abstract

In this paper, we present a model for the late-time evolution of the universe where a dark energy-dark matter interaction is invoked. Dark energy is modeled through an holographic Ricci dark energy component. The model is embedded within an induced gravity brane-world model. For suitable choices of the interaction coupling, the big rip and little rip induced by the holographic Ricci dark energy, in a relativistic model and in an induced gravity brane-world model, are removed. In this scenario, the holographic dark energy will have a phantom-like behaviour even though the brane is asymptotically de Sitter.
