• Phase space
• Dark energy
• f (T, T) gravity

In this paper we explore f (T, T), where T and T denote the torsion scalar and the trace of the energy-momentum tensor respectively. We impose the covariant conservation to the energy-momentum tensor and obtain a cosmological f (T, T) respectively. We impose the covariant conservation to the energy-momentum tensor and obtain a cosmological f (T, T) model. Then, we study the stability of the obtained model for power-law and de Sitter solutions and our result show that the model can be stable for some values of the input parameters, for both power-law and de Sitter solutions.
