摘要: A general formula is calculated for the connection of a central metric w.r.t.\ noncommutative spacetime Lie-algebraic type. This done by using framework linear connections on bi-modules. The further used to calculate corresponding Riemann tensor and prove Bianchi identities certain symmetries that are essential obtain symmetric divergenceless Einstein Tensor. In particular, obtained Tensor not equivalent sum scalar, as in commutative case, but addition traceless term appears.
