Description
In this talk, I will focus on non-singular solutions that can be realized within Horndeski theories, whose distinctive structure allows for controlled violations of energy conditions without introducing pathologies. I will review the typical stability challenges that arise at the level of linear perturbations and highlight how they constrain such solutions. Finally, I will discuss illustrative cosmological models that avoid an initial singularity and comment on their characteristic features.
