In this way comes Lovelock’s theory, which is the generalization of General Relativity and describes a gravitational theory in arbitrary dimensions. The next step is to include more degrees of freedom by admitting torsion in the theory and thus we arrive at the generalization of Lovelock’s theory called the Cartan-Lovelock theory. Another generalization that can be obtained is to stay in 4 dimensions and include a scalar field so that second-order equations of motion are obtained in the metric and the scalar field, this theory is known as Horndeski’s theory. In this thesis, we explore a step further from this generalized theory by including torsion and obtaining the Cartan-Lovelock-Horndeski theory.
