摘要: The Palatini variational principle is applied to the action integral of Jordan-Brans-Dicke theory gravitation. An affinity differing from Christoffel symbols by an additional third-order tensor obtained. Field equations with covariant derivatives and Ricci defined respect this are found. Rewriting these using derivative constructed yields physically equivalent those Jordan, Brans Dicke.
