摘要：

The vacuum field equations are solved in a V2 following from the scale-invariant gravitational Lagrangian pound sterling = R(k + 1). For pound sterling = R2, exactly six solutions exist. Just one of them breaks the scale-invariance and has indefinite signature. For k --> 0, nontrivial results also arise. Their relation to two-dimensional quantum gravity is discussed. For pound sterling = F(R) a Birkhoff-type theorem holds.
