We analyse Einstein equations with a scalar field by means of a computer algebra program, testing for the existence of alternative Lagrangians. After proposing an algebraic test, we apply it to both the cases of minimal and nonminimal coupling between gravity and the scalar field.

Abstract
We analyse Einstein equations with a scalar field by means of a computer algebra program, testing for the existence of alternative Lagrangians. After proposing an algebraic test, we apply it to both the cases of minimal and nonminimal coupling between gravity and the scalar field.File in questo prodotto:
