First integrals in the Brans-Dicke cosmology
arXiv:1901.00388
Abstract
The work presents the frst and the second degree Darboux polynomials, Jacobi's last multipliers as well as the set of frst integrals for Brans-Dicke cosmology. Algebraic invariant sets are constructed. First integrals are visualized for some particular values of the parameter.
