Contribution

It critically examines existing model-independent approaches in cosmology, identifying key issues and shortcomings to improve their reliability.

Abstract

Since the number of dark energy models have rapidly increased over the last years, some model-independent methods have been developed in order to analyse the cosmological evolution in a phenomenological way. In this manuscript, we analyse some of these approaches and their shortcomings to provide reliable information.
