摘要：The concepts necessary for an algebraic construction of a gravity theory on noncommutative
spaces are introduced. The q-deformed diffeomorphisms are studied and a tensor calculus is defined.
This leads to a deformed Einstein-Hilbert action which is invariant with respect to deformed
diffeomorphisms.
