  "abstract": "We carry out a canonical analysis of the coupling of a 4-dimensional effective action that arises from a dimensional reduction of a 7-dimensional BF theory to the Palatini action in 4-dimensions with cosmological constant, focusing on homogeneity and isotropy in all involved fields. We employ Ostrogradsky’s methodology because of the presence of second time derivatives. Through the analysis of consistency conditions, we identify three distinct and consistent possibilities. In all these scenarios, we explore the solution of second-class constraints in terms of pairs of canonical variables. Similarly, Hamiltonian analysis is performed only for the 4-dimensional effective theory. By explicitly solving the second-class constraints in terms of the canonical coordinates, we demonstrate that one of the admissible configurations in the analysis–namely, the coupling of the effective action to the Palatini action–is fully equivalent to the case in which only the effective action is considered in the absence of gravity.",
