摘要：
We consider scalar-tensor and multiscalar-tensor theories of gravity and their formulations in the Jordan and the Einstein conformal frames. After constructing a generic multi-scalar tensor action, we derive its full equations of motion as well as equations for homogeneous isotropic cosmological models in the Jordan frame. We use methods of dynamical systems in the case of two scalar fields to determine the fixed point and conditions for its being an attractor.
