Gravity model analysis
WebDec 24, 2024 · In its standard formulation, the Newtonian gravity model has three important general characteristics: • It describes the interaction between two bodies; in a system consisting of more than two bodies (e.g., three), its dynamic trajectory may lead to chaos as proven by Poincaré in 1890 (see Stewart 2002 ). • WebWe analyze the cosmological solutions of f(T, B) gravity using dynamical system analysis where T is the torsion scalar and B be the boundary term scalar. In our work, we assume three specific cosmological models. For first model, we consider $$ f(T,B)=f_{0}(B^{k}+T^{m})$$ , where k and m are constants.
